Let´s say that you are on your late 20s, early 30s, you had a rewarding professional career without breaking your back but you were never really passionate about it. You look back and you realize that you were successful working in several different areas but you are not really an specialist in any of those areas. Now you are half way through a part-time MBA, and you could use it to specialize in one area or maybe start doing something that you are passionate about.
The problem is that you don´t know what you are really passionate about since you like (not love) many different fields. It´s like knowing that you have to marry ONE girl (the market rewards specialization), but you like ALL of them without really loving any of them.
