Know or listen to those who know.
To know oneself, one should assert oneself.
Well done is better than well said.
It's always too early to quit.
After a storm comes a calm.
What you do today can improve all your tomorrows.
Begin to be now what you will be hereafter.
If you think you can do it, you can.
Wherever you are - be all there.
Be thine own palace, or the world's thy jail.
But to me the bottom line is the more education you can give yourself, and the more preparation you can do, the less chance of failing.
