I've been going for a walk a couple of evenings each week, and I'm amazed at how just carving out a small amount of time for recreation can change the tone of the day. These thirty minutes are transformative for me. My mood and even my posture changes when I get back from a walk -- I'm not hunched over, even when I sit at the computer -- and I just feel like I can stand taller in more ways than one. Being in nature for a short period of time in the day is uplifting and rejuvenating. Seeing a ladybug crawling along, or some beautiful wild flowers blowing in the wind, listening to the birds, looking up at the sky, all things I don't get enough of. The walking itself does the body good, but there's no doubt this is good for overall well-being. I'm going to pencil in a walk at least twice a week. Its a great way to end the day, and hard to talk myself out of, since its only 30 minutes. Give it a try if you aren't already doing something like this. I wish I had sooner.
