I had a TV set and a typewriter and that made me think a computer should be laid out like a typewriter with a video screen.
I sold my most valuable possession, but I knew that because I worked at Hewlett Packard, I could buy the next model calculator the very next month for a lower price than I sold the older one for!
I think everything I have done in my life, my reasons at the time were right no matter how things worked out.
