Dude, you're 25. You're just at the very start of your life.

But since you're worried about "being behind" and "not making it", perhaps you should reflect on what you mean by those things. You're "behind" what? How do you define success and failure?

In any case, my advice to you is that you're just getting started. It's far too soon to seriously fear failure in your life. The important thing in anything isn't the current state, it's the trendline. As long as you are moving in the general direction of your goals, you'll be fine.
