The reason behind

The necessity of doing something useful always drives us beyond our limitations, because everytime you start an activity you ask yourself about the utility of it, and if you don't find what you were searching for you will constantly keep searching for the opportunity to abandon it and start another activity which you suppose beneficial. However, the problem is ; if you think this way you will never find what you are looking for, unless you establish a goal before starting any kind of activities, which will keep you oriented towards your goal, you will finally find the activity useful, you will actually benefit from it, and it will be a modest source of happiness, thus your personality will be improved, and you will surpass yourself and your limitations little by little.
