To do so, you must take into consideration a number of factors and variables that include your physical skills, your appearance, the amount of weight you want to lose or gain and whether you would settle to building up your strength, flexibility and endurance. There are various physical activities that fit various physical or fitness gains, and it would be appropriate if you would first do a little research about them or more advisably, seek the help of experts and professionals. Even if the effort is raised 100 times, 1,000 times or 1 million times, if the they are really unachievable, nothing will do to make the athletes realize them. Short term goals are far better motivation tools than long term, but they can be used to eventually lead to longer-term goals and targets. Goals should reflect priorities. If you don't have a ready answer, don't be surprised. Even the greatest of the philosophers who had ever lived succeeded only in making this question more profound. Why? Because the answer lies not in simply knowing what's your purpose in life but lies in discovering what's your goal in life. The last one is only possible if you have already gone through the process of goal setting. You would certainly prove to yourself that doing so would never be a waste of time and would help you achieve more determinedly your desired outcome. Know yourself better. Be sincere and honest when you think of yourself, your ability, your talent, your skill and your capacity. By so doing, you would be able to avoid the trap of overestimating or either underestimating yourself. Each person for sure has his or her own other life aspects like social, life, sex life, family life and spiritual life. Each individual has his or her own set of priorities. That is why effective time management would really be necessary so people would easily and effectively meet targets and beat deadlines with greater ease. What you will need is a procedure in which you can monitor each step of the goal so as to make the necessary revisions. And since goal setting is never done to isolate yourself from the rest, make it a habit to surround yourself with people that share your vision. This will help you in motivating more of yourself into achieving what you have decreed for your self earlier.
