The only thing scarier than failing is succeeding. (Note that I said scarier, not worse.) Because every success takes you to the next level. There's no finish line, the stakes just keep getting higher.
Now that it worked, now what? There are real people counting on you now. Your investors expect a return now. Your employees are buying houses.
You're not experimenting, you're executing.
If you go down, real businesses stop.
This is the idea that pays for the bad ones. This is the one that justifies your philosophy. And it's success will enable more success, or so you think.
But it's not done.
