Never complain and never explain.
If you think you can do it, you can.
To know oneself, one should assert oneself.
Always desire to learn something useful.
The secret of getting ahead is getting started.
Only the educated are free.
The wise does at once what the fool does at last.
By failing to prepare, you are preparing to fail.
Without hard work, nothing grows but weeds.
Either you run the day or the day runs you.
Asking the author of historical novels to teach you about history is like expecting the composer of a melody to provide answers about radio transmission.
