Trust that little voice in your head that says "Wouldn't it be interesting if..."; And then do it.

What can I do? What should I do? What shouldn't I do? When do I do it? How do I do it? What are the consequences? What if This? What if That? Will it be successful? Who can I depend on? Where do I get this? How will I manage? Will it be ok?

Endless questions and the answers to them all can only be found only when I just do it.
