To leave in search of yourself, of your real needs, is easier when you don't have to justify yourself to anyone, when there are not too many people bestowing you their attention.
In my ideal world, no child would suffer. Charitable instincts would prevail. There would be global acceptance of all different types of people.
You have to have enough respect for other human beings to leave their lives alone. If you admire that life, build it for yourself. Don't just try to come in and take somebody else's life.
