Having a dream results in development of self motivation thoughts. Unlike cause, dream is more real and reachable. Concentrating on things that can help you reach your dream serves as a great motivator. It is difficult to stay focused and make yourself work, if you do not know why you are doing it. Would a football player be motivated, if there was nothing to play for? Just like a football team needs a trophy, you need a goal to reach. It will keep you on track and will make your mind think in the right direction. Having a dream means not to be distracted by things that are not important. However, if your dream is not great enough, you may, at some point, think that it is not worth trying and give up. Dream of something really worth making efforts!
