<span>Successful means being able to understand what is important to you. If we spend our time and effort trying to meet somebody else's idea of success, and ignore or belittle any of our contrasting views, then we will find ourselves exhausted and unhappy. One cannot be successful until they have reached this mindset of happiness; it is not possible for one to be successful unless they are happy with their goals and achievements. Successfulness is the ability to understand what goals you strive for in life, and prioritizing so that you are able to achieve them. Realizing what is truly important to us is a major step towards achieving personal success.</span>
