A simple command, but it's one that I follow all the time. Meditation in its simplest form could be boiled down to this. Breathe in, breathe out. It centers me. Keeps me in the moment. Being in the moment is one of the most important things I personally think anyone can do. Breathing in I take in all of the stresses and worries I'm occupying my time with and then with breathing out I try my best to let them all go. For example, when I'm taking a test I sometimes find myself worrying about failing and so I begin to turn my mind on overdrive and think of all the consequences of failing and how I could fix it after I fail. But while I'm stressing I'm not even focusing on the test which is actually something I know and something I could very easily get an amazing grade on. So I breathe in, and breathe out. Keep this in mind. It helps, a lot. When running I sometimes find myself taking on the mindset that I'm in pain, that I'm just slogging through the miles, that I HATE it. But that is unnecessary and wrong to think those things. We need to breathe in and then breathe out to switch. To switch our minds to accepting the pain and enjoying it, that these miles are awesome and that I'm having a great time, and that I love what I'm doing right there in the moment.
