It is a very beneficial thing to realize that you make a difference. The only thing better than this is to act as if what you do makes a difference. Realizing it is like school learning. You learn about something and you can approach an understanding of the subject, or at least a better understanding than you had before, but it isn’t until you apply the knowledge that it becomes real to you. By acting as if, you put it into action.
This doesn’t mean successful accomplishment is immediate, but by practicing the activity and the knowledge behind that action, success is just a matter of time.
Believe that you make a difference to other people. You do. It is virtually impossible to interact with other people and not make some kind of a difference. You will.
This leaves only one thing. What kind of difference will you make? This is a great question and here’s a better one: What kind of a difference would you like to make? Intention is important. Think of the action as the car and the intention as the fuel that feeds it.
One last point. There are a lot of things that you do. If you will act as if whatever you do makes a difference, you will find that it does. Apply the question of what kind of a difference would you like to make to each.
