Granted. You get the most impressive and inspiring idea of which you will know, once you made it, it will change Knytt Stories forever. People will see your level and they'll learn from it. It'll be the new standard. You start working on it but within the first day of this multi-year project, you already discover this isn't only nearly impossible, you have no clue how to even start. As a result, you now have this awesome idea in your head, and Petals II will never ever get finished because whatever you add, it will not make it nearly as good as that awesome idea you had.
I wish I could easily do song-writing. You know, come up with lyrics for songs that work well for a song.
