The joy of knitting socks is that halfway through you have a finished object. The frustration of knitting socks is that you still have a second (hopefully identical) sock to make.
The joy of knitting a blanket (composed of blanket squares) is that partway through you have a finished square. The frustration of knitting a blanket is that you have lots more squares to do.
(I am proud of myself for estimating exactly half the ball of yarn when I knit this square. It makes the rest of my blanket calculations easier.)
