Motion is important. I see too many entrepreneurs focused solely on the "boat" - their product, their business, whatever problem is nagging at them in that moment. If it's a problem, they spend too much time thinking about it. If it's a product, they spend too much time perfecting it, designing it, and adding to it. They think that success depends on some specific output, or one specific result.
This is not only good advice for entrepreneurs, but for the thousands of bright people looking for work.
Don't stay still.
Don't be paralyzed.
Keep moving and good things will happen.
