Have a 15-minute “silly” break :P
View your childhood photos. It will surely bring back happy memories!
Snack on “Cocoa-nut” bananas. Slice a couple of bananas, roll each slice in cocoa, shake off the excess, and dip in grated coconut. Yum yum!
Burn an incense stick. Breathe in jasmine, vanilla or sandalwood scents to help you relax.
Try “Black and Blue” meditation. Visualize your breathing in blue, calming air and exhaling black, angry air. Drain stress out of your body with every breath.
Give yourself a foot massage. Roll a tennis ball under your bare feet. It’s a technique that gets to all those reflexology pressure points.
Go for a quick jog around your neighborhood for a change of scenery.
Have fun! 
I'm a teacher but sometimes patience is not my virtue. I'm moody but caring, sensitive but thoughtful and generous to a fault.
