Being is so significant that it is irreplaceable. You are just yourself. Do something that comes out of you - not to assert, but to express! Sing your song, dance your dance, rejoice in being whatever nature has chosen you to be.
Sometimes in life, things happen that will knock you back. Hell, you may get beaten to your knees but you must never ALLOW this world to knock you down! Conjure up all the strength you have and drive through whatever it is keeping you on your knees. Build up the strength and your knees may never buckle again!
