Without hard work, nothing grows but weeds.

Be gentle to all and stern with yourself.

Only the educated are free.

The secret of getting ahead is getting started.

It's always too early to quit.

Go for it now. The future is promised to no one.

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

To know oneself, one should assert oneself.

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