I think the takeaway message I've learned from school, and in life, is that there will always be someone who is better than you at something. I'm always envious of my peers who are better at (X), and I forget that if I reflect on my own skills, I'll find (Y) that I can do better.
You'll likely never find someone who is better than you at EVERYTHING.
Everyone has strengths and weaknesses. I think there's a certain beauty in that, because by working together, we get the benefit of being good at X and Y. This is why cofounders who have complementing skill sets are so successful.
Find something you like, and just do it. Connect with people that do things you don't like to do or are not as good at. The rest will fall in place.
