Work it out with a paper clip
A lot of Change Your Thinking is either common sense, or stuff I've already heard on Doctor Phil.
That's not to say it's not worth reading - it's absolutely fantastic to be reminded of common-sense stuff that's not really that common.
And sometimes there's a completely new gem from out of the blue, like this:
An exercise I occasionally do in my workshops is to ask participants to come up with fifty possible uses for a paper clip. Sounds impossible at first, but when I reassure people that our record is 102, the creative juices start to flow ... When we believe that solutions exist, we are much more willing to look for them and, as a result we are much more likely to find them.
