To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
Go for it now. The future is promised to no one.
If you think you can do it, you can.
If you've got a talent, protect it.
Wherever you are - be all there.
After a storm comes a calm.
If you can dream it, you can do it.
Only the educated are free.
Never complain and never explain.
