The key, for me, is to consider it like any blog or social network. I never made a buck from them, and neither should I expect to make anything here. If I do, that's just a massive bonus.
So, I think the secret is, to do your best, be honest, speak from your heart. If you're lucky - it'll make you rich. If not, you'll never have any regrets knowing you did your best.
That's some awesome advice! I completely agree, and will definitely keep that in mind!
