It's always too early to quit.

Without hard work, nothing grows but weeds.

If you've got a talent, protect it.

To know oneself, one should assert oneself.

Never complain and never explain.

The most effective way to do it, is to do it.

Begin to be now what you will be hereafter.

The wise does at once what the fool does at last.

Well done is better than well said.
