Ask HN: Should I quit my job

I am working at a late stage startup with good compensation and the stock payout would be pretty good if it could exit.

The problem is I find my job to be boring and unfulfilling. I don't think I learnt much over the past year. Now I am almost depressed after days after days' bug fixing (mostly) and some uninspiring tasks.

I need two more years for the stock to be fully vested. Now I am thinking if I should quit so at least I could find another startup at least I could have interesting work to do.

Would love to hear what you guys thought! Thanks!
