So what is an entrepreneur?
A puzzle solver.
Any entrepreneur worth respecting utilizes vision as his greatest resource. The job of an entrepreneur is to put together the pieces, in any order, to create his vision. That's it, simply put. There's a large range of flexibility with puzzles and the same goes for visions of businesses or movements.
The process of a puzzle is exploratory by nature. You try, you do something wrong, you try again, and eventually you complete the puzzle. The pieces may be set, but you don't know what they look like until you find them. You need X, Y, and Z pieces, but you only need them eventually.
The same principle applies to entrepreneurship. Do you have a vision for something? Take one step. Then take another. Keep going like that and you'll be far ahead of the pack.
Now look at the picture on the box and pick up a piece.
