I just ran across a story about Warren Buffett and Bill Gates. When they were asked what was the most important factor in their success they both said "focus". It made me think immediately of what we are trying here, to focus on a niche, a specific group, offering a specific service, rather than trying to offer everything to everyone which is still what I find myself inclined to do with students. I found this encouraging - if it's good enough for them, it's probably good enough for me.
