It seems there's yet another term for a "scanner" or a "renaissance soul": a "slash".
It was popularized by Marci Alboher. (Ooh, ain't she pretty.)
At least it's similar, although admittedly somebody with more than one career is not exactly the same as somebody with many interests.
Marci has some interesting columns, including this one about financing a career change.
Here's a radical viewpoint from our Finnish hacker friend, TTL:
Geeesh .... how wussy can these people get?
"financing a career change"? I gotta go puke ... ok, I'm back.
Here's the algorithm (please relay info to Marci Alboher):
Step 1: Ask self, do I love what I am currently doing? Do I find it fun? Would I do it even if no one paid me to do it? If yes, goto end. If not, continue to step 2.
Step 2: Stop immediately what you are doing. If it's an employment relationship, resign immediately.
Step 3: Ask yourself, what would I most want to do in life? Don't question your answer. Not even if its something illegal or immoral.
Step 4: Whatever your answer in #3, start doing it.
Step 5: If you run out of money, stop eating, sell belongings, beg, steal or borrow. But don't stop.
Step 6: When you have lost 20% of your weight, you can no longer see clearly and all your friends have left you, you know you are on the right track. Don't stop!
Step 7: Now living on the streets, health problems, busking to stay alive, DON'T STOP! You are almost there!
Step 8: GREAT SUCCESS! You have more money than you can spend. Everyone wants to know you. Suddenly all your old 'friends' are back (tell them to f*ck off!) People call you "lucky" (tell those to f*ck off, too!)
Step 9: Do whatever you like. Without apology.
Step 10: Go to step 1.
I'd say it'd be a good thing to think of all this before starting a family.
