I read lot of posts expressing frustration at getting job or complaining about office colleagues or office environment. My advise is to stop worrying about matters that are beyond our control. These worries are like sitting in a rocking chair. We do keep moving the chair, but it does not take us anywhere. Everyone has different skills like decoration. cooking, gardening, teaching. Why not use these skills. The problem is selling. For this digital marketing is an extremely helpful tool. I am 63 years and want to learn the technique. Can somebody suggest sites those provide basic knowledge of this tool.
