What person should you to be to achieve your goal? First, you should choose a goal and determine why is it necessary for you? Than find out what problems you should overcome to achieve this goal. Also necessary to make plan and to follow this plan. I don't think that person needs some quality like Superman. You just have to do the work which necessary for achieve the goal. I think you need to be a little stubborn and not think about the result. You should to do this work everyday, every week and if it necessary every year. Some people say that you need to be persistent, hardworking, ambitious, determined, obstinate, strong-willed, tolerant, energetic… it so… but I think it is not the most important. Much more important to be relaxed, fun but at the same time a little stubborn and to have great interest to his goal. Also to work according by plan and you will reach the goal.
