One piece of log creates a small fire, adequate to warm you up, add just a few more pieces to blast an immense bonfire, large enough to warm up your entire circle of friends; needless to say that individuality counts but team work dynamites.
Practice opening and closing your eyes a few times a day, with the awareness of letting go of your dark feelings to the brightness of the light.
