Each day at about 12:30pm I go for a walk, but I carry a special little recorder voice Dictaphone.
Breathe in the air, and be inspired as you are out and about. Start to speak your mind into your voice recorder and let you throughts and emotions all come out. You will be amazed as you do this, and get better at it, how much good info you can come up with. It is how I sometimes come up with 10 articles in a 30 minute walk.
For me it is alot easier to talk what I want and just play it back and type and have everything already set to go. Other than just sit there staring at a blank screen like a boy lost in the wilderness.
As you are walking and talking you might even get a weird look from the crowd of onlookers as you walk by talking to yourself...but I say just wave to them, or tip your cap to them & realize they are the suckers working their 9-5 JOB. Not you.
Hope this helps.
P.S. this is great to get out from behind the desk and get some excercise too.
