Goal setting help to achieve more and reach your potential. Without goals, things just do not seem to get done at all or nearly as fast. Goals help to push you, to set progress markers and to make you accountable to do things that you would otherwise give up on. Whether a work goal, an atheletic goal or leisure activity, goals are beneficial in all areas of life.
However, I have found that there are also a couple of things to watch out for when setting goals. The first is the need to set new goals once the initial goal is reached. The second is to keep the goal small enough so that it does not overwhelm.
