Is your college experiences a good indication of how your life will be?

Because if it is, I'm not too optimistic about the future. My college experience has been blah. I've had great semesters academically speaking, and crappy semesters academically speaking. I'm not depressed about it anymore. I just keep going, but yeah it hasn't been perfect. I know it seems like a really stupid question, but am I going to be like this after college to? I feel like I never have it together. Idk if that's my own insecurity or if that's how it really is. Does it get better?
