Leap, and the net will appear.
Either you run the day or the day runs you.
Problems are not stop signs, they are guidelines.
If you've got a talent, protect it.
Never complain and never explain.
Well done is better than well said.
Without hard work, nothing grows but weeds.
The dog that trots about finds a bone.
To know oneself, one should assert oneself.
The secret of getting ahead is getting started.
