You never know what motivates you.

What you do today can improve all your tomorrows.

Do not weep do not wax indignant. Understand.

I can, therefore I am.

The wise does at once what the fool does at last.

It's always too early to quit.

Quality is not an act, it is a habit.

Know or listen to those who know.

Go for it now. The future is promised to no one.
