I don't know if you currently do BJJ or are only thinking about it, but I started when I was older, and may never get a black belt. But, I have moved up over the years and know that my belt color changing or getting a stripe on an existing belt doesn't suddenly make me a different person. After chasing goals for so long, BJJ is an amazing reminder that it really is the journey that matters. It's shaped me to be a better person regardless of an arbitrary belt color.
