There is only one direction to go and that is forward. Even if we wanted to, we cannot go back to the past, we can not change what has happened, we can not do things differently then we already have done them. The only place to make changes to our lives is in the now, this is the moment of change, this is the time to get it right.
Knowing what right is isn't easy. Actually we can't know for sure what is right so we have to guess. It helps if we know what we want and what our values are since these two perspectives give us a framework to define right and wrong. Even without knowing what we want, even without knowing what we value there is still one question we can ask to help us understand if a choice is right: "Does it help me move forward without knocking anyone else down?"
There will be times when we are in competition with others for a job, a grade or a prize and it would seem in these situations that knocking the other down would be right for us. However, the right way to compete is to focus on our own skills not the skills of others. We move forward not by holding others back, we move forward by moving forward. By pushing against the wind we grow strong.
