You have a lot more impact as a founder over whether that business succeeds than you would ever have over a wager in roulette or a 4 game NFL parlay on Sunday.
Both are risks. Only one is a gamble.
I do think that there's a bit of overlap in that part of the mentality of people who gamble and people who start businesses. You have to accept that there's a good chunk of luck with starting a business, and also acknowledge that if you don't have that luck that the business will likely go belly-up.
What I was getting at is I am personally a coward. I don't say this with pride, and this isn't some attempt at humble-bragging or anything, it's a dig at myself, not entrepreneurs.
Sometimes being a coward isn't a bad thing, if nothing else I don't waste my money at casinos, so that's good. But because I'm so terrified of losing money, and so terrified of anything involving "risk", I feel like I took the cowards way out by working for BigCos at a desk job instead of trying to build my own thing. Sometimes I'm a little jealous of the people who can throw caution to the wind.
