Learn to meditate - it helps you to stay in the present moment
Visualize yourself in some picturesque location which you would love to visit
Touch something which calms you like a piece of satin ,silk or a pet
Learn some breathing techniques
Look around you to notice the good things of life
Drink some herbal tea
Try self massage
Take time out from your daily routine
Try a musical detour
Take an attitude break dump your should's and must's
