I haven't done any small paintings for a while. So I did one last night. When I started the setup, my mind was completely blank. Our life is so complicated nowadays. We constantly jump from one project to another, which have no relationship what so ever in between. After I shoveled my engineering stuff away and pick up my art thingy, I felt really odd and empty. "You must have an art concept before you paint". That was what I learned and taught. But sometime, I really don't have any idea. I just paint.
