It's always too early to quit.
Be kind whenever possible. It is always possible.
Problems are not stop signs, they are guidelines.
If you've got a talent, protect it.
The dog that trots about finds a bone.
By failing to prepare, you are preparing to fail.
Either you run the day or the day runs you.
Without hard work, nothing grows but weeds.
To be a good loser is to learn how to win.
If you're going through hell, keep going.
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.
