If you see a need, then do it, but do it cheap so you can fail without causing any long term damage to your finances. Most likely you'll fail (most companies do after all) so doing it cheap and failing fast are both useful and pragmatic. If you do manage to succeed then bravo. If you don't succeed but you enjoyed it then do it again when you see the next need. Wash, rinse, repeat. If you didn't enjoy it (or if you're looking to gain wisdom) then change paths and go work with or for someone else for a while. Pay attention to their successes and mistakes, be actively involved in their business, and then start your own again.
