I don't remember wasting that much time as a teenager, since if I wanted something, I needed to get a job and work for it. If there was any chance of my bettering the type of situation I grew up on, I had to make sure my grades were amazing. I had to deal with someone else's serious drug addiction in the family, and try to make sense of it, while committing to myself. I don't know if you were ever physically abused as a child because of the lack of drive?
I'm just saying, you may have had the privilege to waste time on someone else's dime, and everything still worked out alright. Not everyone has that. Some of us, if we're not willing to fight from the get-go, we're going nowhere.
Anwyays, congratulations on your post doctoral fellowship.
