I think my brother may have identified the reason for my recent habit of not spacing my words: a defective space bar! He had the problem too, and noted that only emphatic punching on the spacebar resulted in the desired space. We need a new keyboard!
I also realized (well I already know this but I need to explain this to other people) something about myself. I am an all-or-nothing type of person. My life is informed by my binary view of success. There are no partial successes, only total failures. I take risks and shoot for the home run. My view is that if you are good and prepared that you can make a good living this way. The failure is disheartening, but the success when it comes is an intoxicating drug. Men kill (literally) to taste of that type of success.
