Here's one of my favorites that I sold to National Review magazine that I happened to run across in my files . . . I actually saw a poor sap like this at Union station in Washington, D.C. back in the '80's - - - and people ask: " Where do you get your ideas ? " . . .
I think you have to be very observant, usually the ideas are not given to you in complete form, ready to use, but by free-association, it's amazing what is actually out there floating in the ether - - - the secret is to "pluck" one going by, put it in your folder - - - and come back later to it and keep tweaking it - - many times, something comes up - - - they are out there.
