Positive all the way

My workmate Mr. Silvam shares with me some thoughts this morning. He say:" If we are facing obstacles, do not be agitated. We should remain cool or take it easy." I tell him that all surely have problems either big or small.
He further say:" If someone ask:" How are you?", Please do not answer :" I am not good>" even you are not that good. Because if we say " no good ", our mind will ready become no good."
I tell him:" Yes, we have to turn all negative thoughts to positive one." He say:" Yes, you are right."
This is the short conversation between us this morning.
Mr. Silvam have changed a lot, I believe it is because he has more clearer mind than before.
