Ask IH:11years looking to start the entrepreneurial adventure, what should I do?

Hello everyone. In this post I will try to tell you with my struggle to start a startup and I looking for your advice. I am 26 y/o and for the last 11 years I have been struggling to find my place in the startup scene. I changed my interest so many times from programming web apps to mobile to game development to graphic design. I tried starting some project but couldn't finish them since I tend to perform better as part of a team. I couldn't find a team to join so far so I asking for your advice or if someone will let me join his team even without money. I want to experience the entrepreneurial adventure even if it was partial experience.
