It's always too early to quit.
You never know what motivates you.
If you've got a talent, protect it.
Know or listen to those who know.
After a storm comes a calm.
To know oneself, one should assert oneself.
Only the educated are free.
If you think you can do it, you can.
Always desire to learn something useful.
The wise does at once what the fool does at last.
