The concept may be a basic one to most people, but I seem to have just discovered it:
If you want to love what you do, do what you love.
A simple little phrase that speaks volumes the more you look at it. If you find a way to get paid for your hobby then you have achieved career nirvana. These are the things that you would choose to do in your spare time anyway but now you can make a living with it. Very few people actually reach such an enlightened state. None that I know of personally actually. Most people can start to come close by finding a job that is relatively entertaining and possibly even related to their hobby, but rarely does an individual reach that plateau of "I would do this for free if I was asked, but they keep insisting on paying me!"
I have come to the confusion that I really don't know what my passion is. I have several hobbies that are somewhat encompassing and several others that I would like to delve into more fully given the finances and/or education to do so. I like to work with my hands, but I don't want to be a laborer my entire life. That's the reason I took the job I currently have. I like to create, but I'm not nearly as creative as I would like to be. I like to be a part of where things happen. That I have currently. I am no longer an insignificant part of the machine. Where does this leave me? I have no idea. Maybe it's time to just list what the actual interests are and see what I have.
