I was a quintessential burgeoning nerd at around the age of 5 or 6. My intense interest at that age in all things electrical and electronic in nature set me on my life path. I had a need to know how things worked. I gave myself a vey dangerous electrical shock with a record player that I took apart while it was still plugged in to the wall socket (hay I was only 5 or 6 at the time so....). My other lifelong passion was and is physical puzzles. Relatives would buy them as quick birthday presents and most were disappointed at how quickly I managed to solve them all. I guess the combination of those two interests led me to a good living as a computer-program bug-hunter and creator of enhancements.
I have a lot of other deep interests that were never exploited for personal gain and those may be classified as being either in the arts or in science. You never now what things you are proficient at until you spend years working through just one interest, and interests have a habit of shifting and mutating. It is the ones that persist that will give one inroads to a satisfying and interesting life; in my distinctly uninformed opinion.
