Without hard work, nothing grows but weeds.
It's always too early to quit.
If you're going through hell, keep going.
Do not weep do not wax indignant. Understand.
If you think you can do it, you can.
Wherever you are - be all there.
The wise does at once what the fool does at last.
Know or listen to those who know.
By failing to prepare, you are preparing to fail.
Leap, and the net will appear.
Don't take too much comfort in the fact that you're successful today because tomorrow could bring failure. There's no surety in life.
