"Do I enjoy doing experiments? Can I deal with this stress? Can I do this for a living? Can I do this for life?"
I really think you should read the lecture, especially if you're a scientist. I should admit that I haven't stated "my problem with science" as I mentioned in the title. It's just that this lecture is one the most well-written ones regarding this sensitive (if I may say so) topic and reflects my thoughts in a much better way than I could have ever done myself.
It's the last paragraph that really moved me. It didn't answer any of my questions but it helped me realize that it's not the 'failing' experiments, the stress or the money that are the problem. It's beyond all of that. It's the way science is done. Having said that, I think I am a novice in the field and hope that my opinion is one of a pessimist's and not a realist's.
Here's the paragraph:
"So I have just one wish for you--the good luck to be somewhere where you are free to maintain the kind of integrity I have described, and where you do not feel forced by a need to maintain your position in the organization, or financial support, or so on, to lose your integrity. May you have that freedom."
Please tell me that there is some hope of finding that freedom and making science fun again.
