My son would like a GPS for his life. It's not a bad idea. I wouldn't mind having one, too.
Imagine what it would be like: this nice voice (probably with a British accent) would say things such as, "You will experience frustration in 1.5 miles." or "Great joy at next exit." It might say, "Take the next job ahead," or "bypass this relationship for the one around the corner."
I want my son to know that he has a kind of built in GPS. I am trying to help him tune into his internal voice. I want him to "trust his gut." It's hard work, this tuning in. I am still working on it. But when I listen, I know it's there. And it's usually right.
