I don't think anything is unrealistic if you believe you can do it.

What is it that makes us suppose that we can more easily do twice tomorrow what we didn't do once today!

Realize that the privilege to work is a gift. Love of work is success. Be thankful that every morning that you get up that you have some thing that must be done (whether you like it or not).

There are some things you can give another person, and some things you cannot give him, except as he is willing to reach out and take them, and pay the price of making them a part of himself. This principle applies to studying, to developing talents, to absorbing knowledge, to acquiring skills, and to the learning of all the lessons of life.

We can run away from where we are, but not from what we are.

We must carry things beyond conversation to conclusion.

Your direction is more important than your speed.
