Walked for 30 min. this morning and felt like I could walk a lot more but I was on a time crunch for work. I played tennis tonight (doubles) for a couple of hours and felt so strong energy-wise. I can't believe exercising a few times in a week can make this much difference...it must be my imagination. This is weird, totally weird, but I am actually looking forward to getting up in the morning and walking!! Something is happening to my mind....I like it!
