On LinkedIn there is a #AdADay challenge, where creatives from all over the world have one day to think up and execute an ad for a one sentence brief.
I don't do these every day...so I kinda cheat. I do the ones that I find especially fun or challenging. These are meant to be super quick (20 minutes max), so they aren't the best. But they are a lot of fun, and are keeping me sharp in quarantine.
Fun Fact: There really is a McDonald's at the "North Pole."
