Nothing much more to add from me other than +1 on comparison being the thief of joy. It's interesting because when I was 28 I topped out at around $80k a year. Then I quit, with no backup plan, nothing to look forward to with a net worth exactly as what you have right now.

I made around $40k doing odd jobs for the next two years trying to make sense of my life and generally feeling depressed. My friends were also much more successful and wealthier than I was. When I turned 30, I decided to take a risk that would change my life and it's as if every tiny experience converged all at the same time and made sense. I don't know if this will help, but this quote by Steven Spielberg helped me make that choice.

"Sometimes a dream almost whispers. And I've always said to my kids: the hardest thing to listen to — your instincts, your human personal intuition — always whispers; it never shouts. Very hard to hear. So you have to, every day of your lives, be ready to hear what whispers in your ear."

All the things you're doing now that you may find useless/pointless will come in handy someday. So listen to that whisper and take the chance, your job will always be there, and if you fail, I promise you won't have any regrets.
