The surest way not to fail is to determine to succeed.

The difference between a successful person and others is not a lack of strength, not a lack of knowledge, but rather a lack in will.

The only medicine for suffering, crime, and all the other woes of mankind, is wisdom.

Years teach us more than books.

A wise man learns by the mistakes of others, a fool by his own.

The art of being wise is knowing what to overlook.

Arriving at one goal is the starting point to another.

We are what we repeatedly do. Excellence, therefore, is not an act but a habit.

Most ‘impossible’ goals can be met simply by breaking them down into bite-size chunks, writing them down, believing them, and then going full speed ahead as if they were routine.

In everything the ends well defined are the secret of durable success.
