It's always too early to quit.
Problems are not stop signs, they are guidelines.
Only the educated are free.
You never know what motivates you.
Do not weep do not wax indignant. Understand.
The dog that trots about finds a bone.
To know oneself, one should assert oneself.
Things do not happen. Things are made to happen.
If you've got a talent, protect it.
Leap, and the net will appear.
Attitude is your acceptance of the natural laws, or your rejection of the natural laws.
