Never complain and never explain.
I can, therefore I am.
Know or listen to those who know.
Either you run the day or the day runs you.
It's always too early to quit.
If you've got a talent, protect it.
Only the educated are free.
Wherever you are - be all there.
By failing to prepare, you are preparing to fail.
Begin to be now what you will be hereafter.
There is as much wisdom in listening as there is in speaking - and that goes for all relationships, not just romantic ones.
