To know oneself, one should assert oneself.
What you do today can improve all your tomorrows.
The wise does at once what the fool does at last.
Do not weep do not wax indignant. Understand.
Know or listen to those who know.
By failing to prepare, you are preparing to fail.
Wherever you are - be all there.
Never complain and never explain.
Problems are not stop signs, they are guidelines.
I can, therefore I am.
