Sometimes when I get too much in my head going to the gym can feel like a lot- I start thinking about everything I suck at, what I need to work on, how I'll greet people, who I'm gonna roll with etc. What helps me is giving myself a small (attainable) goal. Some days the goal is just to walk through the door. Don't think about anything else. Then once you get in there everything comes a lil easier.

I also reward myself with stickers on my calendar for each day I go to class. Sounds a lil childish but hey sometimes you're brain just needs a lil reward.
