Goals can be set unrealistically high. When a goal is perceived to be unreachable, no effort will be made to achieve it. Conversely goals can be set so low there is no challenge so the person puts out no effort. If achievement cant be measured, then your self-confidence will not benefit from goal setting, nor can you observe progress towards a greater goal. Set precise, quantitative goals.
Goal setting can be unsystematic, sporadic and disorganized.
Too many goals may be set, leading to a feeling of overload. Remember that you deserve time to relax and enjoy your success. An old Chinese proverb says a trip of a thousand miles starts with only one step. A person must be able to see themselves reaching the goal and if they can't they must make it easier. The second option is to break it down step by step and figure out exactly what you must do to reach the goal.
