I think this is a false choice.
Every successful founder I know thought his or her venture was not that risky — at least when she started it.
Sometimes, oftentimes, 6–9–12–24 months in, you see just how risky it is.
But great entrepreneurs see white space, gaps in the market. They assemble a team to attack it. And they rarely see it as all that risky in the very beginning.
Even though the odds certainly say it is.
So … if your gut says it’s too risky, that you are worried about going ‘all in’ … don’t do it. That’s a sign not to, in my experience at least.
