original ideas aren't THAT hard to come by, you just don't realize that joke that lasted 20 seconds could be made into a full feature length film if you tried. on the other hand there's nothing you can make that won't be compared to another thing of the same category TWT

It's also easy to come up with a neat concept for a simple drawing, only to find out that someone else already did actual worldbuilding based around that. Twice.
