Try it today - when you feel the urge to grumble, whine or whinge, think of something you're grateful for instead. If you take a good look at your life you will find lots to be thankful for, for example, you have the ability to read this opportunity right here! Consciously exercising gratitude, and being appreciative of what you have is the key squashing those pesky complaints that want to bubble up and keep us focused on the negative, when we could be celebrating the positive. Go on, try it.
