Never complain and never explain.
If you can dream it, you can do it.
Problems are not stop signs, they are guidelines.
To know oneself, one should assert oneself.
By failing to prepare, you are preparing to fail.
Wherever you are - be all there.
To be a good loser is to learn how to win.
Without hard work, nothing grows but weeds.
The secret of getting ahead is getting started.
If you think you can do it, you can.
