Success is defined differently by everyone. You may be more interested in pursuing financial success, whereas someone else may find more personal joy with relationship and family success. However you define it, success will remain elusive unless you take the time and effort to pursue it.
Part of reinventing yourself is figuring out exactly what you want from your life experience. Most people do not get what they want from their life because they have never spent the time defining exactly what it is that they do want.
Give yourself the gift of time everyday just to visualize, imagine, and daydream. Think about what your perfect day would be and then pretend that it is that way in reality. The more you do this, the better you will get at knowing what feels right for you at this point in your life.
