this a whole disaster process was that I

this a whole disaster process was that I had a fantastic biology course that year

had a fantastic biology course that year

had a fantastic biology course that year so it’s my freshman year of high school

so it’s my freshman year of high school

so it’s my freshman year of high school I had this really enthusiastic and

I had this really enthusiastic and

so that year living in that environment

so that year living in that environment where i had that course i was totally

where i had that course i was totally

where i had that course i was totally psyched up about and that teacher who

where the headquarters of all the big biotechnology firms were at the time I

biotechnology firms were at the time I

biotechnology firms were at the time I came up with the plan so the plan was

came up with the plan so the plan was

came up with the plan so the plan was going to be my course for the entire

going to be my course for the entire

going to be my course for the entire rest of my career I was going to go to

rest of my career I was going to go to

rest of my career I was going to go to college major in biology I was going to

college major in biology I was going to

college major in biology I was going to go to graduate school get a PhD and then

go to graduate school get a PhD and then

go to graduate school get a PhD and then I was going to go work for one of these

I was going to go work for one of these

I was going to go work for one of these cool biotech firms where you can cure a

cool biotech firms where you can cure a

cool biotech firms where you can cure a disease and get rich doing it so looking

disease and get rich doing it so looking

disease and get rich doing it so looking back I’d say I know my new myself at

back I’d say I know my new myself at

back I’d say I know my new myself at that point well enough to know that I

probably know some people like that so

probably know some people like that so for the next 14 years I’ve

for the next 14 years I’ve

for the next 14 years I’ve all of the plan I did go to college and

all of the plan I did go to college and

all of the plan I did go to college and major in biology I did go to graduate

major in biology I did go to graduate

major in biology I did go to graduate school and get the PhD I met and married

school and get the PhD I met and married

school and get the PhD I met and married my husband while I was at it so

my husband while I was at it so

my husband while I was at it so everything was perfect except that it

everything was perfect except that it

everything was perfect except that it wasn’t because the further along I got

wasn’t because the further along I got

wasn’t because the further along I got on the plan the more time I spent in the

on the plan the more time I spent in the

on the plan the more time I spent in the research lab doing science and the more

research lab doing science and the more

research lab doing science and the more I started to feel like I kind of wanted

I started to feel like I kind of wanted

I started to feel like I kind of wanted to be doing something else and that was

to be doing something else and that was

to be doing something else and that was a really strange thing for me to be

a really strange thing for me to be

a really strange thing for me to be thinking at that point because the plan

thinking at that point because the plan

thinking at that point because the plan had been to do research and I was doing

had been to do research and I was doing

had been to do research and I was doing research so what was the problem I tried

research so what was the problem I tried

research so what was the problem I tried switching labs I tried spend it’s more

switching labs I tried spend it’s more

switching labs I tried spend it’s more time paying attention to my feelings and

time paying attention to my feelings and

time paying attention to my feelings and what I found was that no matter where I

what I found was that no matter where I

what I found was that no matter where I was working my favorite parts of

was working my favorite parts of

was working my favorite parts of research were not designing the

research were not designing the

research were not designing the experiments and getting the results back

experiments and getting the results back

experiments and getting the results back which is what scientists are supposed to

which is what scientists are supposed to

which is what scientists are supposed to be totally psyched up about my favorite

be totally psyched up about my favorite

be totally psyched up about my favorite parts were teaching the younger students

parts were teaching the younger students

parts were teaching the younger students how to do their experiments and then

how to do their experiments and then

how to do their experiments and then presenting our result of conferences so

presenting our result of conferences so

presenting our result of conferences so across my mind if what I like most is

across my mind if what I like most is

across my mind if what I like most is the teaching and the describing you know

the teaching and the describing you know

the teaching and the describing you know maybe what I really want to be doing is

maybe what I really want to be doing is

maybe what I really want to be doing is teaching not research and that was a

teaching not research and that was a

teaching not research and that was a pretty complicated thing for me to be

pretty complicated thing for me to be

pretty complicated thing for me to be thinking right then because scientists

thinking right then because scientists

thinking right then because scientists get kind of an attitude about people who

get kind of an attitude about people who

get kind of an attitude about people who leave research you know to get from the

leave research you know to get from the

leave research you know to get from the point where you’re a high schooler who

point where you’re a high schooler who

point where you’re a high schooler who loves a science to the point where

loves a science to the point where

loves a science to the point where you’re a junior investigator running

you’re a junior investigator running

you’re a junior investigator running your first research lab it’s about 15

your first research lab it’s about 15

your first research lab it’s about 15 years worth of work and not everybody

years worth of work and not everybody

years worth of work and not everybody makes it the whole way you know the

makes it the whole way you know the

makes it the whole way you know the hours are long the pay isn’t great and

to get a good professor job in today’s

to get a good professor job in today’s job market your work can’t be just good

job market your work can’t be just good

job market your work can’t be just good enough it’s got to be amazing so there

enough it’s got to be amazing so there

years in on the plan looking at washing

years in on the plan looking at washing out research and I was feeling really

out research and I was feeling really

out research and I was feeling really insecure about that so I kind of tended

insecure about that so I kind of tended

insecure about that so I kind of tended definitely mentioned the idea you know

them are bacteria and then if you wanted

them are bacteria and then if you wanted to see viruses you would have to even

to see viruses you would have to even

to see viruses you would have to even zoom in again because viruses are

zoom in again because viruses are

zoom in again because viruses are another order of magnitude or more
