To know oneself, one should assert oneself.
The secret of getting ahead is getting started.
It's always too early to quit.
If you think you can do it, you can.
Do not weep do not wax indignant. Understand.
Wherever you are - be all there.
Only the educated are free.
The dog that trots about finds a bone.
Be thine own palace, or the world's thy jail.
Go for it now. The future is promised to no one.
In my teaching, I enjoyed creating models to clearly communicate my thoughts.
