Be kind whenever possible. It is always possible.

Without hard work, nothing grows but weeds.

The dog that trots about finds a bone.

The secret of getting ahead is getting started.

Well done is better than well said.

Begin to be now what you will be hereafter.

It's always too early to quit.

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

To know oneself, one should assert oneself.
