I disagree. To be good in business, you need experience, which comes with time and mistakes.

Hacking imho either comes naturally or it doesn't. If you can't see the appeal of an apparently pointless activity eg. code golf, then you're probably not a hacker, and never will be.

This doesn't mean you won't be a good entrepreneur - if anything it could even help; since you don't waste time on silly (but fun for a hacker) things.
