Stand for something. Make your life mean something. Start where you are with what you have. You are enough.
Security is mostly a superstition. It does not exist in nature, nor do the children of men as a whole experience it. God Himself is not secure, having given man dominion over His works! Avoiding danger is no safer in the long run than outright exposure. The fearful are caught as often as the bold. Faith alone defends. Life is either a daring adventure or nothing. To keep our faces toward change and behave like free spirits in the presence of fate is strength undefeatable.
If you never try, you'll never know. You are what you manifest.
