What keeps you going everyday ?

Being a college student but not being the best at studies, I constantly wonder what life could've been if I'd taken a different life path. If it'd been less mundane, would everyday have been exciting. I am kind of confused at the moment, for what I stand for except my selfish interests. I feel like I'm old enough to have identified what I want, but I can't stop thinking about the fragileness of my current identity. I'd like to know if there's a sure shot way to keep building myself in the ways that I want, but not in the ways that hurt me or others around. I'm sorry if this is a tangent but feelings of insufficiency I think, lead to this overthinking, "need for a greater answer" behavior, and a greater answer to keep going on in life and strive to keep getting better. Hyderabadis I feel you guys are quite chill, and would love to know what you think about all of this!
