What Can You Expect From Life at This Age?

I was doing a lot of thinking these past couple of weeks, and I honestly kept wondering to myself, what is appropriate to expect of yourself and your life at this age? Using myself as an example, I'm 19 years old and at this stage of the game it's easy to feel like you're failing or you're ahead of the game. You go on social media and you see so many people your age either far ahead of you or the same place you are, some of us are buying houses or in love; and some of us are deep in debt trying to survive college. How do you know when you're in the right place? To my understanding, the place you're in right now is exactly where your suppose to be, but how do you know that you're satisfying every gift that's been given to you? How do you know your are using every opportunity you have to your full advantage? How do you know you're doing enough? Comment what keeps you guys motivated and confident in your life!
