I can’t remember where I heard this but ever since I’ve heard it, I can’t get it out of my head, it goes something like this, “There comes a time in every cartoonist’s life where they realise that they don’t have enough time on this Earth to complete all the ideas they have in their head.”
This has happened to me (I thought it was just me but now I know it’s not). And, I suppose, there are two ways to respond. The first is to crawl into a hole and weep. The second is to get working. I’ve chosen the second.
