If you're doing that well at your age already, give yourself a major pat on the back. I regret not treating myself that way at your age. For what it's worth, I'm finally going to Law School at 36 years old after feeling pretty much exactly like you when I was 24 and wanted to go the first time. I actually believe I'll perform 100x better with going now than I would have as my younger self.... I've worked in advertising, commercial insurance, and the production industry, getting to the top of my game there, and got married and had two kids. It's amazing what time will do to bring your confidence up.

I promise if you give yourself a break, you'll thank yourself later.
