Every human being thrills at the thought of achievement. The idea means different things to different people. To you it may mean physical health; the ability to walk, run, play, to engage in activity. To me, it may mean abundance; money, a home, a car - opulence. To another, achievement may mean education, or the ability to get along with people. Whatever achievement or happiness may mean to you, you desire a larger amount of it, a closer affiliation with it.
The ability to control your experiences and have them result in happiness, prosperity, and success lies in your own mind and the way you use it. This means you control your own experience - you are really in charge of your affairs and the way they are to develop.
Let us sum it up this way: My thought is in control of my experience and I can direct my thinking.
Read that again and then say it aloud. It is a most astounding statement and at first it may seem farfetched. But because you are a modern person with an open mind ready to be shown what you may not at first understand - even what does not seem entirely believable - you will be willing to take that statement under consideration and hear the reasons for it. Certainly you do not have to believe it, and you do not wish to until you have investigated it, heard the arguments in its favor, and observed whether or not it works for you after you have given it a fair trial. That is the way the intelligent mind approaches any new idea.
