To know oneself, one should assert oneself.
Never complain and never explain.
The secret of getting ahead is getting started.
The dog that trots about finds a bone.
Problems are not stop signs, they are guidelines.
It's always too early to quit.
You never know what motivates you.
Without hard work, nothing grows but weeds.
Who seeks shall find.
If you're going through hell, keep going.
Sympathy with nature is part of a good person's religion.
