When did belt colours stop being important to you?

For me, it was getting the blue belt. I had been a white belt for a long time due to injury, club changes, moving areas etc.and i got desperate to get the white belt off me.

When i was promoted to blue, the sense of achievement was huge...but surprisingly fleeting.

It changed nothing for me other than i stopped worrying/focusing on what was around my waist. Ironically i think that actually made my techniques better over the next couple of years.
