Without hard work, nothing grows but weeds.
If you think you can do it, you can.
It's always too early to quit.
The secret of getting ahead is getting started.
Problems are not stop signs, they are guidelines.
Never complain and never explain.
The wise does at once what the fool does at last.
To know oneself, one should assert oneself.
The dog that trots about finds a bone.
Either you run the day or the day runs you.
The distance between insanity and genius is measured only by success.
