You hear people talking about this mysterious 'flow' state.
Where you're working on something that you love, and the hours just fly past and you don't even notice.
This happens to me when I draw.
I get started, and then I just can't stop. I think, ok. In twenty minutes' time I'll pack up. But the next time I look up to check the clock, an hour and a half has gone by.
So, I'm sorry this post isn't more interesting, but I was working on this drawing!
I'll try to get it finished tomorrow so that I can share it with you.
