Do something that you love. Whatever you're going to do is going to be tough enough. Find something that gets you so excited that the sun can't come up early enough in the morning because you want to go do your thing.
If you want something, go get it. Period.
The world is your oyster. It's up to you to find the pearls.
Find something that you love. Something that gets you so excited you can't wait to get out of bed in the morning. Forget about money. Be happy.
