I have friends who still engage in magical thinking in their 30s. It doesn't impede their ability to function and helps them get out of bed in the morning; ergo, they aren't schizophrenic either.
They do, however, give one Hell of a tarot reading. Uncanny, really.
Uh-oh. Sounds like I still engage in my fair share of magical thinking.
I don't think it's anything to worry about.
