Problems are not stop signs, they are guidelines.

You never know what motivates you.

The dog that trots about finds a bone.

If you think you can do it, you can.

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

Be gentle to all and stern with yourself.

Without hard work, nothing grows but weeds.

Quality is not an act, it is a habit.

To know oneself, one should assert oneself.
