Hehe, I do the same. My current blue deck is worn out but can't bring myself to open a red one. It's mainly because if I open the red one I'll think the blue one is useless and I don't want to do that. It's why I started another thread asking what everyone used their old decks for.
Hmmm need to find something to watch for 2 hours until quizmania comes on. Better go look through the dvd collection.
As a random question, does anyone else try to measure their progress? I don't mean excessively like graphs n charts

But just like how much you've learnt or progressed in the past week/month etc. I mainly ask as I read a lot of posts on here and do find myself "behind" a lot of people. Not sure if I'm going slow? Or there are other reasons that my tired mind hasn't picked up yet.
