Yeah...although it is somewhat unrealistic...I encourage you to go for it. I have a very steady, very boring job that pays well but I basically hate. This works well for me because I have a family. If I was single there is no way in a million years I would continue to work the job I am in.
I believe that although money is important, if you have enough to support yourself that is all you need. Go and do what you love even if it does not provide you with wealth. It will satisfy you in more important ways.
