I’m an Art Director/ex-copywriter who honestly doesn’t even like advertising.
I’ve never come up with an idea by using a post-it sticker. Usually I just say “wouldn’t it be cool if…” out loud and sometimes it is cool but most usually it’s just weird.
Add me on LinkedIn if you want to chat. In the meantime, below is a collection of some “wouldn’t it be cool if…” thoughts that actually turned out to be kinda cool.
