I want the experience of creating and nurturing something that from nothing can pay my family's bills. I want the experience of working in a close team again. I want the experience of being able to ride market problems.
If things work out? I may want money/freedom/time, but all of that really boils down to experiences as well: the experience of owning a jet, learning to scuba dive, seeing my kids grow up from very close (instead of commuting to a job).
It's all about experiences folks. When you die, it doesn't matter how much you've saved or what you might have been able to do because of your freedom. What matters is your choices and the experiences they provide.
