The only thing you have to think about when building a career around what you are passionate about is what you need. Creating stuff is far cheaper than you may think than you think.

And what do you do with the remainder of the capital? Buy a yacht? The difference? Figure out what you really need to do and it will take all the pressure out of growth.
