By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
Wherever you are - be all there.
The dog that trots about finds a bone.
Without hard work, nothing grows but weeds.
Be gentle to all and stern with yourself.
Go for it now. The future is promised to no one.
Do not weep do not wax indignant. Understand.
To be a good loser is to learn how to win.
You never know what motivates you.
