@browncoat - I always structured my meditation sessions after a guided meditation technique they taught us in high school one year. It involves imaging that I'm walking down a staircase and becoming more relaxed with each step, sort of similar to the way people talk during a hypnotism session, except I'm telling it to myself.
And then I imagine myself to be by the ocean and I basically just sit there and look at it in my head. I know it sounds a bit cheesy, but it's very relaxing and I find it useful for clearing my mind.
Apparently doing regular meditation is very good for you, but I've never not done this regularly, so I don't know what benefits it necessarily has had for me.
