If you think you can do it, you can.
The most effective way to do it, is to do it.
Do not weep do not wax indignant. Understand.
If you've got a talent, protect it.
To know oneself, one should assert oneself.
If you can dream it, you can do it.
Begin to be now what you will be hereafter.
Wherever you are - be all there.
Who seeks shall find.
Know or listen to those who know.
