If you're going through hell, keep going.
Who seeks shall find.
The most effective way to do it, is to do it.
Things do not happen. Things are made to happen.
Know or listen to those who know.
After a storm comes a calm.
Be gentle to all and stern with yourself.
Either you run the day or the day runs you.
Never complain and never explain.
By failing to prepare, you are preparing to fail.
Have convictions. Be friendly. Stick to your beliefs as they stick to theirs. Work as hard as they do.
My experience has been that work is almost the best way to pull oneself out of the depths.
