When I graduated from the University of Chicage Graduate School of Business with my MBA, the convocation speaker was Richard Thaler ( http://www.nber.org/vitae/vita507.htm ) one of the foremost proponents of Behavioral Finance. He said that the only advise he could give us was to 'find your cello' - He was referring to Yo-Yo Ma, one of the finest cellists in the world who knew from an early age that he wanted to be a cellist. Prof Thaler's view was 'do what you love" to find real success.
I was thinking about that recently when Jeremy mentioned to me that a friend of his had started a wine bar and was really happy. To those people who can actually do this, more power to them. However in some ways this is a very easy answer and may even be disingenuous and can lead people to draw the wrong conclusions/ decisions. For example, often what you love to do may not sustain you economically - what then?
I have heard of another view - learn to love what you do- that's often harder because that may not be what you originally thought you wanted to do but it pays the bills and you can actually get to like it as well. How so? Well by finding something within work that maps to your interests and trying to grow that aspect. Or simply just getting better and better at what you do so that you become an SME. When you do something well, usually you also tend to like it.
Usually it takes both growing the piece that interests you as well as getting better at what you are required to do. Not easy of course but can be done and frankly for most of us, is the present day reality.
You can of course still pursue your "real' passion but as a hobby- when I was very young I wanted to play Cricket for India:-) I wasn't good enough though but I still play Cricket occasionally and it remains fun.
Now I'm going to register for a Cello class:-)
