switch career!

I just read an article about how people like to switch over from a successful high paying careers to persue their dreams.This housewife who was 40 was all set to a boring middleage life,but she chose to persue a flying class and is now a pilot :) .I wonder what all we would like to do if we chose to switch career?hmmm...i am still pondering on this.But,i come up with different answers each time.There was this doctor who switched from being a successful practitioner to a TV actor(now this needs courage).But somehow most of us donot have the courage to make such a huge switch.Also the people mentioned in the article were mostly middle aged .So,they would be sufficiently free from responsibilities and monetory problems.I think i will wait for my middle age ;-) to approach so that i can jump to a new career :)
