A typical example would be a trader who likes to trade just one setup that may only occasionally occur in ES, so he scours many many markets looking for his setup. These are the guys who really work for a living and probably have a better chance of success. I traded nothing but ES for many years but had to take some huge risks that I would not take now. I would certainly not call what I was doing sensible. The only thing that saved me was I had to withdraw money every month to pay bills and that kept me from adding size to my stupidity when things were seemingly going well.
