To know oneself, one should assert oneself.

If you think you can do it, you can.

It's always too early to quit.

The dog that trots about finds a bone.

Problems are not stop signs, they are guidelines.

The secret of getting ahead is getting started.

If you're going through hell, keep going.

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

Without hard work, nothing grows but weeds.
