It's always too early to quit.
Well done is better than well said.
Go for it now. The future is promised to no one.
Be thine own palace, or the world's thy jail.
To know oneself, one should assert oneself.
If you've got a talent, protect it.
If you think you can do it, you can.
The most effective way to do it, is to do it.
Never complain and never explain.
Without hard work, nothing grows but weeds.
I've done an awful lot of stuff that's a monument to public patience.
