There is only one security, and when you've lost that security, you've lost everything you've got. And that is the security of confidence in yourself; to be, to create, to make any position you want to make for yourself. And when you lose that confidence, you've lost the only security you can have... Self-confidence is self-determinism. One's belief in one's ability to determine his own course. As long as one has that, he's got the universe in his pocket. And when he hasn't got that, not all the pearls in China nor all the grain and corn in Iowa can give him security, because that's the only security there is.
Don't wait until everything is just right. It will never be perfect. There will always be challenges, obstacles and less than perfect conditions. So what. Get started now. With each step you take, you will grow stronger and stronger, more and more skilled, more and more self-confident and more and more successful.
