I am currently a scientist working in a university. I have a PhD in Biochemistry. I have applied and got accepted by a pharmacy school.
I was quite "idealistic" about science profession before, thinking scientists pursuing their research interests supported by government agencies. However, after I really worked, I realized doing science is much more complicated and stressful than that. I normally work 60 hours/week, paid 50~60K. I need to get fund to support part of my own salary. If I could not get the fund, I could be easily kicked out. The competition in this fiels is ridiculously high, and almost hopeless for me to obtain a tenure job. I have two kids. I cannot imagine what I can do to support my family if I lose my job.
I am an organized person, and want predictable future. That's why I decided to shift to Pharmacy. Since I am not in school yet, I could not say whether I regret the decision yet.
