I've done some Christmas shopping but am not completely done yet.
My shopping method is:
"power walk through the mall until you see things that catch your eye and seem like you should buy them".
This is very effective.
If there were a job where I could teach a course on this I would apply for it(part time)
I think it would be fun to power walk through a mall with a bunch of people and yell,
"Just grab things! Follow your heart!"
have no one in the mall know what the hell we were doing.
