Excellent. This is a dangerous pitfall that can snatch defeat from the jaws of victory. If you've based your businesses around a boat, and you're convinced there's a market for it, then don't go turning it into a plane at the last minute, or you might end up with neither.
If he was a real entrepreneur, he would have made it with the boat... Nice story though!
A nice reminder. Shit, where did I put that propellor...
