I often have great ideas that I'm sure, if I keep at them, will turn into something great that I can start a proper cartooning career on, but every time, I eventually run out of steam on it. I lose motivation, or have another idea that seems better.
Either way, I've managed to stick with "This is Normal", and "To Let" is being resurrected in the form of "Not Quite Dead", so there are two things that I have actually managed to stick with for all this time. I just hope I can keep at them.

I have a gallery folder for it.
