Totally agree, I'd like only to add that, what many artists (and in general people who pursue their artistic passions) had, compared to the agerage workin-joe, is TIME. The only way to understand your passions is by having time to observe your world, to reflect on people's actions, to contemplate nature. If you have to work (because you're the bread-winner and have 2 children already and an house to pay), your only glimmer of hope is to have already found your passion during your younger years. Finally, your energy levels going on are never gonna be your current ones. Keep that in mind. And I say that as a man who had a fair number of interests, never had time to really pursue them, and now has to to a work I hate and have no remaining passion at all.
