If you are setting your goals alone then self-motivation is the most important factor for achieving a goal. There are some goals which are short term whereas some other are long term, If you goal is short term then you have to work harder with greater strength and quick management and you will get the result after a short time but if you are striving for long term goals then the most important weapon you should be equipped with is patience and save your energies for long time by motivating yourself... Commitment with yourself or with the group members will make you perform better for the achievement of goals. When you are committed to the people or with yourself then there is the responsibility on you which helps you to perform better and speed up your performance. Keep a check on your performance and if you are performing better than try to be the best but if your performance is going down then review you're planning and check your mistakes. More difficult the task to achieve is more..
