Can you elaborate a little on the business (without disclosing anything you're not comfortable with)?
Are you the founder? Revenue, clients, contracts, business in place? Are you looking to startup with partners (and as such, co-founders)?
You're right about the ability to execute vs. the entrepreneurial drive - the latter is some kind of genetic thing 😀 I'm on my 4-5-6th businesses, starting doing my own thing in my early 20s, never looked back.
That being said, I was involved in a startup that raised some decent capital, crashed and burned, then another startup over the last 6 months, an old friend and partner, and I wasn't really happy with where in put me in terms of my "life goals". So be prepared to _not_ succeed, and determine your contingency in advance (as well as your risk <> reward)
