All people go through moments in which we feel the urgency to analyze the decisions we have made throughout our lives.
We can read books that speak from different points of view, about what we should do to find what we really want.
That feeling of emptiness, occurs when during our life we have been following "what other people tell us" that "we should do" because it is "socially correct". Now, it is not that following what society indicates is bad, on the contrary, it is part of our essence as social beings ruled by rules to guarantee coexistence with others. The problem comes when following what others say ends up "drowning" any original gift that we have, which in the long run causes us frustrations.
Having a life with a purpose, implies that what we do with our life generates passion, enthusiasm, joy, whatever the plan we have (have a business, children, a couple, develop some talent, religion, etc) make us feel full and satisfied with ourselves.
Not because for some accumulate material wealth is synonymous with success means that for everyone it is, people are different, we have different nuances, characteristics, dreams, desires, projects, among others, the question is, which ones are yours ?, the only one valid answer are those dreams and longings that are really born of your essence, that are born from your heart.
Have an excellent day.
