Regular exercise is a great way to help you keep a positive outlook on things. Keeping yourself in good physical shape relieve you of a lot of daily pain and cuts down on your worries about your health, and feeling better physically can help you feel better emotionally. Plus, the time spent exercising is time that you can quit thinking about work. If you’re doing something that takes a lot of concentration, then you have to focus on that instead of your work, and if you’re doing something that lets you simply clear your mind, then you have a chance to unload some of your worries and aggravations from the day and feel better by the end of your workout.

And I’m not just saying that because I ran the Kyoto Marathon yesterday.
