Limited resources force you to make do with what you've got. There's no room for waste. And that forces you to be creative. - Jason Fried

Starting a business on the side while keeping your day job can provide all the cash flow you need.

What you do is what matters, not what you think or say or plan.

"That would never work in the real world." You hear it all the time when you tell people about a fresh idea.

This real world sounds like an awfully depressing place to live. It's a place where new ideas, unfamiliar approaches, and foreign concepts always lose. The only things that win are what people already know and do, even if those things are flawed and inefficient.

Scratch the surface and you'll find these "real world" inhabitants are filled with pessimism and despair. They expect fresh concepts to fail. They assume society isn't ready for or capable of change. Even worse, they want to drag others down into their tomb. If you're hopeful and ambitious, they'll try to convince you your ideas are impossible. They'll say you're wasting your time.

Don't believe them. That world may be real for them, but it doesn't mean you have to live in it.
