The 20 minute method doesn't involve just thinking. You write at the top of the page' MY PURPOSE IN LIFE', and then you just start writing. Listing things off as they pop into your head. It usually takes 20 minutes, but for some it takes longer. Mine took 1 hour, and 40 minutes. When Steve said, you keep writing until you cry. I was thinking it was going to be a crying with a feeling of frustration of sorts, but when it happened it was totally unexpected, and quite profound. It's not like anyone said, "You must climb mount such and such, in order to even come close to snatching the remotest clue". It's an easy thing.
Perhaps so many are avoiding trying it, because of it's very simplicity. They've got it in their heads that, "NAH! It can't be that easy to find out my PURPOSE IN LIFE". I'm looking for something much HARDER than that. I mean, it's got to be more difficult than that. Afterall, this is my whole purpose in life we're talking about, here. That's huge. Simply writing until I cry? That's silly. Why should I have to cry? I mean. I don't want to have to cry. Crying means I feel bad, doesn't it? Will I feel bad? Don't only girls cry? I'm not a girl. Will I cry like a girl? Won't that mean I'm a woos? I mean, only wooses cry. Right? Right. Now, That's not my thing. I think I'll just rome around in the world for awhile longer, and look, there's a can on the ground. I'll kick it along as I walk, that way it'll look like I'm doing something. As long as I don't have to do that writing things down until I cry, thing."
Try it! You'll like it!
