As a former human resources professional it intrigues me why some people are more 'successful' than others. By 'successful' we are referring to an innate ability of some people to set and achieve worthwhile challenges for themselves.Here we are using the word "challenge" and not goals. A challenge may be a goal, but not every goal is a challenge. Challenges stretch us beyond where we are and generally require us to embrace learning something new.Very often it is the learning process - or lack.
