Without hard work, nothing grows but weeds.
If you're going through hell, keep going.
Wherever you are - be all there.
The most effective way to do it, is to do it.
To know oneself, one should assert oneself.
To be a good loser is to learn how to win.
Do not weep do not wax indignant. Understand.
If you can dream it, you can do it.
Always desire to learn something useful.
Never complain and never explain.
