1. Perfectionism kills art. I find that if I criticise myself, it spoils the fun. You can get paralysed by analysis - it takes all the playfulness away.
2. Narrated Aisha, Ummul Mu'minin:
while she was on a journey along with the Messenger of Allah (peace be upon him):
"I had a race with him (the Prophet) and I outstripped him on my feet.
When I became fleshy, (again) I had a race with him (the Prophet) and he outstripped me. He said: This is for that outstripping."
