I want to start a serious business but I dont know what I am doing? I want to learn.

I have read a couple of books about businesses. Other peoples money etc.

I realize really, I am 24 years old with no experience in this stuff.

I wanna start something serious at some point, but I wanna really know what I am doing first. I cannot justify spending two years on my first business which will likely fail, while it could instead focus some energy for 2 years in education. And then use that knowledge as a point to make one to be successful.

I am thinking about getting a business associates degree….

Thoughts on what i should plan at all?
