Mistakes are a part of being human. Appreciate your mistakes for what they are: precious life lessons that can only be learned the hard way. Unless it's a fatal mistake, which, at least, others can learn from.
Look upon every man, woman, and everyone as God. You cannot help anyone, you can only serve: serve the children of the Lord, serve the Lord Himself, if you have the privilege.
"Face the brutes." That is a lesson for all life-face the terrible, face it boldly. Like the monkeys, the hardships of life fall back when we cease to flee before them.
