I decided to leave because I really wanted to do something different than work for a big corporation the rest of my life.  I don’t know exactly what that will be yet, but I know that if I don’t change something, that’s exactly what will happen, change is a good thing.  There’s nothing particularly wrong with working for a big company, and there are actually several benefits.  One thing I noticed was that, with a few exceptions, that the management ranks were filled with mostly reasonable people who had good people skills.  This comes from the “filtering” process that big organizations seem to have in selecting management.   On the other hand, life in a big organization is a bit like swimming inside a glacier; technically, you’re immersed in a large body of water, but, somehow, progress, in any direction, is slow.
