My Most Important Rule in Life

What is my most important rule? I would say that my most important rule is to not let people keep me down. What I mean by this is, when someone has a dream that they wish to fulfill or some sort of goal, they should not let people keep them from fulfilling that goal. An example of this would be if someone's goal in life is to successfully run a marathon, but their parents did not believe that they could do it, they should ignore them. If someone was to do just that, and with a little bit of time and effort, anybody can achieve their goal. Nobody should let any person keep them from doing something that is possible. I am not saying that if someone believes that if they can fly to climb up to their roof and jump off that it will happen, I am saying that with enough time put into their dream or goal, that that person can do just about anything. We were able to get a man on the moon, people didn't think that it was possible, but scientists wre able to make it happen, if that is possible than anything is possible.
