But during all this, did the weight of the glass change?" asked the professor. "NO" "Then what made the arm ache and the muscle( ) stress?" The students were puzzled. " Put the glass down" said one of the students. "Exactly ! " said the professor. " Life's problems are something like this. Hold them for minutes in your head and they seem OK. Think of them for a long time and they begin to ache. Hold them even longer and they begin to trouble you. You will not be able to do anything. It's important to think of the problems in your life, but even more important to ' put them down' at the end of every day before you go to sleep. That way, you are not stressed; you wake up every day fresh and strong and can handle any issue, any challenge that comes your way ! " ,.
