It's always too early to quit.
Wherever you are - be all there.
Without hard work, nothing grows but weeds.
Well done is better than well said.
After a storm comes a calm.
Expect problems and eat them for breakfast.
The secret of getting ahead is getting started.
Who seeks shall find.
By failing to prepare, you are preparing to fail.
Leap, and the net will appear.
However, if a poem can be reduced to a prose sentence, there can't be much to it.
Well, if this is poetry, I'm certainly never going to write any myself.
