Never too late to write a OS

OS is a BIG project comparing to a small program,
so I tried many times and failed.
After that, I'd rather play WOW than thinking to write own OS.
Today I saw another toy OS MikeOs.
In 2006 there are still people writing such foolish things.
Though I said "foolish", It's much greater than what I did in spear time.
I don't know what to do in my spear time, I read game advisement and
went to play game. If I read more news on open source, maybe I will
write more source. I really don't know what to do in my spear time.
