I put other because sometimes I cube when I'm happy. Sometimes I'm angry at how my day went and take it out with some cube averages. Sometimes I feel really serene and relaxed while cubing. Other times I feel I can't concentrate and just get frustrated.
It varies, I would have voted an "all of the above" option.
Also, solves seem so much slower while doing them so I always seem to think "Why is this taking so long?" then I see my time as being under my average.
