Do you know people who always complain?  Whenever I hear someone complain, this story of Rabia Al-Basri comes to mind.There was a time I used to think that if you're complaining all the time, you must be "smart".Because if you're complaining you know what's wrong with the world and implying you know how to fix its problems.But over time I realized the habit of complaining rarely fixes problems.  Instead it only creates more unhappiness not only for us, but also those around us.What we're really looking for is contentment, and the secret of it lies in being grateful.There are so many things to be grateful about that we take for granted. Our family, friends, our health, the food that we eat.Don't let the simplicity of this act deceive you to think that it's not worth doing.It's a practice I often struggle with myself.  But the more I practice gratitude, the better my life becomes.Being grateful for what we have gives focus on what is going right in our lives, and helps to maintain perspective when we face challenges.
