Until now, I have met, as well in the personal and professional life, different people having different perspective over their relationship with success. I’ve seen persons who achieve with a smile on their face their personal and/or professional goals and others who constantly live the insufficiency feeling, despite reaching their objectives. In this context, I refer to a “successful person” as being part of the first category. I have analyzed successful persons around me and I noticed they have in common qualities that differentiate them from the rest of people: the good mood based on the reality they live in, pragmatism and the energy focus on those activities they can handle and control. In other words, you can be concerned about some attitudes of the people surrounding you, but if you can’t control this, it is more useful to concentrate your energy on your attitude towards them.
