To set a goal, you must define your objective as specifically as possible.
Setting a goal is equal to putting all your attention on a desired result. However, it is necessary for the goal to be as specific as possible in order to achieve it. In other words, it is necessary that the person setting a goal thinks carefully about what he/she really wants to achieve and how and when he/she wants to achieve it. The goal must be well-defined in order to define a right life direction. Moreover, a goal must also be as relevant and attainable as possible.
