I don't have a number, just a dream. Achieving that is my goal every day, and sometimes that includes earning money to pay bills.
Ultimately though, money is not everything, and to me life is more than providing for myself and those important to me. But providing for them and myself is also not meaningless.
What's important is why you're doing what you do. For me, I do what I have to do because I love God and I love my family. That makes everything worthwhile. Whether I am rich or poor, happy or sad, in pain or pleasure, I keep going and I'm content because I do my best and that's enough.
