IN the real world, sad and unfair things happen every now and then. But complaining is usually of little use. We should stand up and take control of our own life when we are sick of bad things. This is what the US rock band Skillet tells us in their song Sick of It. The song was released on April 18, 2013. Full of anger, the song encourages us to get away from all the bad things we feel. And that’s when you can make your life better.
