There is little difference in people, but that little difference makes a big difference. The little difference is attitude. The big difference is whether it is positive or negative.
When you do the wrong thing, knowing it is wrong, you do so because you haven't developed the habit of effectively controlling or neutralizing strong inner urges that tempt you, or because you have established the wrong habit and don't know how to eliminate them effectively.
You always do what you want to do. This is true with every act. You may say that you had to do something, or that you were forced to, but actually, whatever you do, you do by choice. Only you have the power to choose for yourself.
You are a product of your environment. So choose the environment that will best develop you toward your objective. Analyze your life in terms of its environment. Are the things around you helping you toward success - or are they holding you back?
Your most precious, valued possessions and your greatest powers are invisible and intangible. No one can take them. You, and you alone, can give them. You will receive abundance for your giving.
