I have been trying to make it a habit to walk for 30 minutes every day at lunch time (I have calculated that I can walk about 1.25 miles during that time) and it feels great. Yesterday, I didn't walk. I can't say I was unable, because I was, I just didn't. I have a list of excuses that won't stand up on their own. Regardless, I didn't walk. and I should have. By the end of the day, depression, self-doubt and paranoia about my marriage had crept in. I wasn't sure what caused it until today, just now in fact. Those feelings were lingering this morning, until lunch time, when I walked. I walked and talked with a friend and now I feel fine. We weren't even venting, just chatting about different things, like the best pizza places around and Twilight. So I realized that maybe my bad feelings from yesterday were from a lack of exercise, lack of getting off my ass and doing something. From now on, I am walking. No doubt about it. This weekend I will go get myself an early birthday present...
