Without passion, any rational person would give up!
If you don't have a passion, you'll give up.
Be honest with yourself and with people always do everything on time. Never give up, go to your goals, even if all the bad. In this life, all really, you only need to do. The more I talk to people, the more I am convinced that in general they have one goal - to become the richest dead in the cemetery.
You have to have a lot of passion for what you do... because if you don't, any rational person would give up.
Whenever you do any one thing intensely over a period of time you have to give up other lives you could be living. You have to have a real single-minded kind of tunnel vision if you want to get anything significant accomplished. Especially if the desire is not to be a businessman, but to be a creative person.
It's hard to tell with these Internet startups if they're really interested in building companies or if they're just interested in the money. I can tell you, though: If they don't really want to build a company, they won't luck into it. That's because it's so hard that if you don't have a passion, you'll give up.
Sometimes life hits you like a brick in the face. Don't give up.
