Things do not happen. Things are made to happen.
It's always too early to quit.
Be gentle to all and stern with yourself.
Always desire to learn something useful.
Begin to be now what you will be hereafter.
By failing to prepare, you are preparing to fail.
You never know what motivates you.
Be kind whenever possible. It is always possible.
The dog that trots about finds a bone.
Quality is not an act, it is a habit.
Even God cannot change the past.
