For almost two years now I've been 'meditating', or what I think is meditating on a daily basis. And I've been teaching people how to do it everywhere I go. Basically you breathe in through your nose on a count of one to ten, breathing out through your mouth saying calm.
To cut a long story short, it works. I was going to precede that with a long moan about all the things that went wrong today, but because I feel calm-ish after meditating for hours, I won't bother and I'll go and make myself a cup of decaff tea.
