Getting rid of the garbage....thoughts on meditation???

   As I outlined in my intro paragraph, I am in the process of getting the garbage out of my life. I have resolved to get rid of toxic relationships and focus on getting myself together... like getting back in school and back in the gym. Trying to figure out how I am going to put myself through acupuncture school. Wondering where I belong in life and what I am suposed to be doing with my life.
   So  I am curious about this thing called meditation..... what is it and how is it done??? I welcome any and all coments about anything.
