By failing to prepare, you are preparing to fail.
You never know what motivates you.
The dog that trots about finds a bone.
Quality is not an act, it is a habit.
The wise does at once what the fool does at last.
Never complain and never explain.
If you think you can do it, you can.
If you can dream it, you can do it.
Be kind whenever possible. It is always possible.
Only the educated are free.
