If you're going through hell, keep going.
Be kind whenever possible. It is always possible.
The dog that trots about finds a bone.
The wise does at once what the fool does at last.
The most effective way to do it, is to do it.
You never know what motivates you.
Never complain and never explain.
By failing to prepare, you are preparing to fail.
Either you run the day or the day runs you.
Expect problems and eat them for breakfast.
If you always put limit on everything you do, physical or anything else. It will spread into your work and into your life. There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.
