The last challenge was a beauty. I really like the idea of offering up a couple of suggestions as it means if you're not inspired by one, you might well be inspired by the other. With this in mind, following are the next couple of suggestions.
The first is courtesy of DrDon (thanks, Don): Signs (as metaphors for life) Don had a picture of a 'Detour' sign as inspiration. But I'm sure you all get the gist.
The second is a favourite quote of mine. It comes courtesy of the great Stan Lee, the man behind such comics as The Xmen, The Fantastic Four and, my personal favourite, Spiderman. The following is a quote Peter Parker's Uncle Ben says to him: "With great power comes great responsibility."
I hope this inspires as much fantastic output as the previous challenge.
