Set your mind on a definite goal and observe how quickly the world stands aside to let you pass.

You are the author of your life. If you don’t like how it goes, write it differently.

Every addition to true knowledge is an addition to human power.

Knowledge is power, and for each level of knowledge; you are held responsible for how you use it.

To acquire knowledge, one must study; but to acquire wisdom, one must observe.

Knowledge is power only when put to use and then only when the use made of it is constructive.

Knowledge speaks, but wisdom listens.

The beautiful thing about learning is nobody can take it away from you.

If opportunity doesn’t knock, build a door.

You and I are not what we eat; we are what we think.
