In my experience, attempting to self-improve your 'personality' in social terms or trying improve your physical appearance is the field where you end up with alot of people unnecessarily suffering and thinking their natural quirks make them somehow an inferior human being compared to say, a non-neurotic 'normal' kid. Or they start by thinking that their current personality is "not them" so they fight against themselves to attempt to become someone charismatic or witty or better at social situations. This many times ends up in severe mental illness, self-hate, anxiety, etc. In these situations, something along the lines of full self-acceptance is imo the right path- it naturally comes to most people, usually not in your teens, but in your late 20s and 30s.

Also, your self-worth should never be based on your social skills or personality, and this is where many quiet/introverted nerdy/smart young folks end up suffering alot in middle/highschool/college. I'm sure many of us realize how artificial the societies of school are after we enter the adult 'real' world. Your popularity seems like everything in highschool, and it may very well be, but you learn real fast how little it matters when you leave school. PG puts it well here in his essay "Why Nerds are Unpopular": http://www.paulgraham.com/nerds.html

In terms of self-improvement for things like your habits and work ethic where your self-esteem/confidence/personality isn't at play, and isn't the 'thing' you are trying to fix, I generally think it's not that big of deal to dislike your current way of life and not embrace yourself. Accepting laziness or whatnot is probably too compassionate for your own good.
