A professor began his class by holding up a glass with some water in it. Held it up for all to see and asked the students,' How much do you think this glass weighs? 50gms!’?....

'100gms!' .... ..'125gms'? One of the students answered “I really don't know unless I weigh it”.
“You are right” said the professor, 'but, my question is: What would happen if I held it up like this for a few minutes? (raised his arm).
“Nothing” the students said.
“Ok what would happen if I held it up like this for an hour?” the professor asked. (arm still raised)
“Your arm would begin to ache” said one of the students.
“You're right, now what would happen if I held it for a day?”
“Your arm could go numb, you might have severe muscle stress and paralysis and have to go to hospital for sure!” ventured another student and all the students laughed.
“Very well said. But during all this, did the weight of the glass change?” asked the professor.
“No”. “Then what caused the arm ache and the muscle stress?” The students were puzzled. “Put the glass down!”  One of the students said.

“Exactly!” said the professor.

“Life's problems are something like this. Hold it for a few minutes in your head and they seem OK. Think of them for a long time, they begin to ache. Hold it even longer and they begin to paralyze you. You will not be able to do anything. It's important to think of the challenges (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, strong and can handle any issue, any challenge that comes your way”!
