It's always too early to quit.
Be thine own palace, or the world's thy jail.
You never know what motivates you.
If you've got a talent, protect it.
Always desire to learn something useful.
Well done is better than well said.
Go for it now. The future is promised to no one.
The secret of getting ahead is getting started.
To know oneself, one should assert oneself.
Without hard work, nothing grows but weeds.
Accept business only at a price permitting thoroughness. Then do a thorough job, regardless of cost to us.
