Personally, I think you kids are too young and inexperienced. You say you have experience, you say you can "do" things. Prove it. Make something ship it, market it, charge for it. Whatever it is, just do it. There is no substitute for proof.<p>I'd even advocate for you to work for a start-up as an early employee. That way you can watch, learn and observe and pick up some experience because there's a lot to learn.<p>The key to being successful, let alone a successful single founder is having a solid understanding of who you are, what you are or aren't capable of, how you see the world, and how you want to make an impact. Some people call it mettle. You might think that you have it all down, unless it's been tested, you just don't know and you'll be always be second guessing yourself. I just don't think you get that unless you've fully entered the "real life".<p>This all goes back to my first point. If you had belief, you would already be doing it instead of searching for validation here. It sounds harsh but I understand your angst. Trust me it becomes managable with time.
