Hi, I sort of wandered into my career. I started in telecom due to a co-op, and then jumped to a cool job making computers for blind people that was both closer to my home, but also offered the opportunity to see many parts of the business. I ended up working on electronics and software in the medical device field. If one has the aptitude for it, I think jobs that are closer to the hardware will have a much longer shelf life. Get a copy of "Horowitz and hill", if you find that book entertaining, you should be fine.
