19 year old college freshman looking for guidance here.

This past year has been one of the best and most influential years of my life. I started taking the gym seriouly and have been seeing results, picked up the guitar and started learning it, went out many times during the summer and developped my bonds with my close friends, and more recently joined a society and took dance lessons in my school.

However, the most important thing that I developped and learned about was myself. I've learned many painful truths about myself, found the source of my fears and insecurities, which led to finally being able to accept who I am as a person. I've also read "Models" and "The subtle art of not giving a fuck", which greatly improved my inner game. I went from being someone who would kill time playing video games, to a passionate, energetic, busy and happy person. In short, I accepted myself, which greatly increased my confidence.

In school, I socialize very easily, and am eager to meet new people and go out of my comfort zone. Sure, I am not yet able to cold approach, but I try my best to maintain eye contact with the cute girls in class, and have tried talking to some of them (which is something I would have never done before)

Despite all of these improvements, I still have this nagging thought in the back of my head telling me that I am not doing enough; that I should step up my game because I don't have much time left. So, my question to you all is: Am I doing enough? Or should I step things up?

TL;DR: Worked a lot on myself through the summer(worked out, went out, followed my passions and accepted myself), but still feel like its not enough. Am I on the right track?
