We're all good at something. And it's fair to say we're all less good at other things. If we're going to be honest, there are some things we're absolutely sucky at!
But all is not lost. Sometimes we can look at things that we're rubbish at (or better yet, things that
other people
are rubbish at) to see how to be more efficient and effective.
For example, I know I drive more economically when my car's computer tells me there's only enough juice in the tank to get where I'm going with not tooooo much spare!
