I have been feeling a bit like the guy in this picture recently. I want very much to be a calmer, more chilled out, less stressed person - but I am not sure how to get there. Every little thing seems to make me feel anxious and stressed out.
I am trying different strategies like going to yoga, writing my morning pages and doing my art diary - all those things help. I suspect though that I also need to cut down on caffiene and cut out sugar.
Some people just seem to be naturally happy, whatever life throws at them. I go through phases of being fairly calm and other times where I am incredibly tense. maybe what I need is a massage or to take up a martial art.
