Due to all these reasons you need a very strong motivator. Something that will pull, push or drag you forward. There is only one thing powerful enough to do that and it's a VISION.

You'll still have to write all of your goals down. Then take that piece of paper and envision yourself after achieving all these goals. In order to succeed you have to become a person capable of succeeding, you have to start thinking like that person, act like that person.

Make yourself truly believe that you are looking into your future through crystal ball. Remember every little detail - expression on your friends faces, proud look in you parents eyes. Feel warm breeze on your face, smell salty air of ocean, imagine your new house on beach.

You need to create a vision so powerful, so desirable, so compelling that it draws all your energy and motivation to it. It has to become an obsession. You have to feel something that a person finding an oasis in middle of desert would feel. Absolute excitement and complete determination. Then any goal becomes possible.
