My own impatience and frustration are definitely the biggest problems I am going to face.
Most of us LBSs always take on the physical side much easier, dropping the weight and getting in physical shape. It's the easier part. I've done the same.
This year I set a goal to make my mind as strong as my body. It's hard to do as there aren't easy-to-find machines at the gym for that. Mind control is so very hard. We won't get there are fast as we got our bodies in shape, but it's a worthy goal for all of us. I've read some on controlling my thoughts, have started yoga, but want to get more into meditation.
