The mini lecture that we started practice with was about right attitudes - ha! We were encouraged to start with the right attitude, but I couldn't, even though I tried. So I stuck to my original resolution, that I would use practice to work through my bad attitude. And I did! Especially with the part where we breathed in a sequence - beginning, middle, and end... matching it to the beginning, middle, and end of each movement in our sun salutations.
I found that toward the end of practice, I was actually looking forward to meditation! And when we were done, I wanted to sit longer!
Talk about a change in attitude - and it was a great feeling. :)
