For me it was a symbol that I put the time in and have a good working knowledge of the basics of my system and can now begin refining and improving my kata, basics, kobudo, etc. I do not have any students so I am still a shodan since 2007 and am happy with that. If I had students that would rightly want to be promoted up that would be different, but for me at this time higher dan levels are not needed or wanted.
