It doesn't make sense to be afraid of the world. It's the world. You're in it. And until you're out of it, you're stuck in it. There are scary things in the world, but face them. Make them scared of you. Or, better still, make them respect you. The respect you earn from your enemies is far greater than any other respect.
Make the most of life. Live it, love it. If you love everyone, then how can people hate you? If they do anyway, then what does it matter? You are you and, as long as you live in the light, they can't change that.
Having green slips of paper doesn't make you rich. Having valuable, fulfilling relationships does. Cherish each one, great and small. They'll save you when you need it most.
