Know or listen to those who know.

Be thine own palace, or the world's thy jail.

Quality is not an act, it is a habit.

To know oneself, one should assert oneself.

Without hard work, nothing grows but weeds.

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

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

You never know what motivates you.

Problems are not stop signs, they are guidelines.
