Go for it now. The future is promised to no one.
Well done is better than well said.
Without hard work, nothing grows but weeds.
Leap, and the net will appear.
To know oneself, one should assert oneself.
It's always too early to quit.
By failing to prepare, you are preparing to fail.
Expect problems and eat them for breakfast.
To be a good loser is to learn how to win.
The dog that trots about finds a bone.
To become properly acquainted with a truth, we must first have disbelieved it, and disputed against it.
The artist belongs to his work, not the work to the artist.
