"I am hopeless at putting this innate ability into practice! I am one of life's eternal bumblers, and my wife often tells people that I am not safe to be let out on my own!"
I don't think that you should worry about not being able to put things into practice. I believe that many very intelligent people have the ideas but don't know what to do with them. One day maybe, you'll have a 'Eureka!' moment and change the way that you think.
Sometimes I think that it would be better not to be 'different' from the majority but then I pick up a tabloid newspaper (not to mention any names here of course - but it shines a lot where I live) and I'm really glad that I am!
