Too many people try to numerically measure success. Most of these numbers relate to wealth, age, intelligence, and seniority. The problem with trying to numerically calculate success is that it doesn’t account for personal feelings, thoughts, and general happiness. That which makes one person happy does not necessarily make everyone happy. Thus, the qualities that make one person successful do not automatically represent a universal measure for success.
As tragic as it is, you must keep in mind that some of the most famous, wealthy intellects fall victim to addictions and suicide. Why? Because even though these folks possess numerous quantifiable elements that society typically uses to measure success, nobody can accurately estimate how they truly feel about their personal lives.
Take away all the excess minutiae. You cannot be successful if you are unhappy, and happiness cannot be measured in numbers. It is impossible keep an accurate score of success when the game is based on personal feelings and beliefs. The key is to realize that success is multidimensional. Just because someone is visibly successful at something they do, does not always mean that they are successful in life as a whole.
To be truly successful you must never suck it up to being unhappy for extensive periods of time. Life is just too short for that kind of sacrifice.
