After forcing myself to try and do this, losing focus, getting bored, getting restless, for several months, I'm finally starting to get something from this. Its been really nice to be clear. I'm not wallowing over the past, I'm not anxious about the future, I'm just "here," don't have to be anywhere and can be in the moment. I've finally understood what it means to "meditate on it."
Don't give up!
