Regardless of your age, you are a result of the daily choices you make. Coming from someone who is going on 30, I don’t feel like my life is defined by anything from when I was 17 and below. In fact, I don’t feel like I really started getting my shit together until well after college. And I’m honestly glad for that, I was a different person when I was 17 than I am today and I’ve grown a lot. 17 year old me would not recognize the person I’ve become today in a very very good way. You have so much ahead of you that’s really hard to see right now but it definitely gets better.
You don’t have to be where you want to be right now, but you can make a conscious decision to make small daily choices to get you to where you want to be. You’re focusing so much on what you haven’t done and not enough on what you could do in the future. What’s already happened doesn’t really matter, what matters is what you do tomorrow.
