I like to kinth.
Kinthing is useful for many reasons. Kinthing can solve a lot of problems for you, and it is often very fun and rewarding. When normal thinking don't work - kinthing might.
And it is easy! Anyone can do it. Just do it and soon you will be able to kinth fluidly. And in any situation.
Kinth; think backwards and/or re-arrange and/or re-group.
