When you finally go back to your old home, you find it wasn't the old home you missed but your childhood.
I've not as yet found one hobby that would absorb me completely when I'm not working, but I have just bought a new apartment and didn't quite bargain for the amount of effort and time and money that that absorbs.
I approach each project with a new insecurity, almost like the first project I ever did, and I get the sweats, I go in and start working, I'm not sure where I'm going.
