Man.. I'm sorry if this isn't the response you're looking for, but the only thing that comes to mind now is that if you enjoy what you do, you'll be more successful then the person who is only looking for success and not enjoying what they do. All the people I listed were people that do this out of passion, and have become successful over time.

I dunno man, I admire them, they don't have a daily job, they have a daily dream.

Yes there are hard times, but everybody has their own difficulties, and when there is failure, you learn and try again towards success. I believe any entrepreneur will tell you that to win, you are going to lose, you are going to learn, and you will eventually be successful.
