I've been programming for about 4 years now. During that time I've become an integral part of my team and have constantly been learning. Despite this I always read comments on HN and feel like there is SO much to learn that I'll never have the time for. I work at a big company and desperately want to leave so I have been dedicating time to prepare for interviews (pretty much just CTCI at this point). Even if I do get better at my interviews and land a job elsewhere, I'm worried that either I'll 1) not be as good as the other engineers there and they will quickly notice or 2) will basically feel the same as I do now. Hopefully the latter doesn't happen. My work environment is pretty negative right now so maybe a change of scenery will help.
Anyway, back to the original question. Does anybody else come on here and feel overwhelmed? Too much to learn, a lot of other people out there who are so much better than you etc. Could be just me, the Bay Area, or tech in general.
Pretend you were working at a company with a hundred engineers. Do you understand how easy it is for every single one of them to simultaneously feel like you do? The React mavens feel like they're just knocking together JS and wonder when they'll be allowed to do real engineering. The backend specialists wonder why they don't understand networking or servers better. The DevOps folks envy folks who build things. The American office wonders why they can't speak foreign languages; the German office marvels that anyone can learn Japanese; the Japanese office worries their English isn't up to the global standard.
There's nothing wrong in specialization -- it's how we stay sane. A very workable and easy to understand formula early in your career is specialize in two things; you don't have to be better at X and better at Y than everyone you meet, you have to be "better at X than anyone who is better at Y" and "better at Y than anyone who is better at X." This is very, very achievable, regardless of how highly competent your local set of peers is.
Also, unsolicted advice as a sidenote, but life is too short to spend overly much time in negative work environments. Assuming the negativity isn't coming from you, changing environments to one of the (numerous!) places where happy people do good work might be an improvement.
