Late night anxiety loop things:
I have friend who is trying to convince me to quit PhD & go industry.
What if my friend is dramatically overestimating the importance of intelligence & ability at getting a high paying job, and underestimating credentials and connections??!!
What if I quit the PhD and I get nothing for a long long time because I have no credentials to flash and no connections to ply?!
I guess stop doubting that I'm smart & capable is a step forward. But we'll see.
