Jim Carrey once said in his comedy routine that many people have certain crazy thoughts. The difference between the sane boring and insane fun is that the sane boring don't act on those crazy thoughts.
Your post had a few errors in it, but don't worry I corrected it
Crazy ideas, eh? I do have a plenty of crazy ideas, but they'll remain only as a crazy ideas.
Once I thought of trying to pick a personality and stick to it for a week, and pick another personality the next week, until I had rotated through all the personalities in that given system (10 types... it was not MBTI). I thought it would be an interesting experiment, but gave up the idea since my friends would probably thought I was crazy or something. I dun wanna be crazy, no sire!
I also thought once I could find a religion of my own.. something much more modern than what christianity is. But then I thought of all the trouble it would make, and just decided to keep my teachings to myself.
