Living a life

I used to tell my students "u should lead a life not living a life "to make them to achieve their goals.When one is young such statement has a meaning. But now after retirement it has no meaning for me. Sometimes I feel my life should come to an end. Life is becoming more monotonous. I am losing interst in evrything, even in gardening, getting new plants. Do your duty without expecting the fruits of your work, Says Loed Krishna. What duty? I have done away with it as the Children are settled. No body will miss me. But I am not lucky to go.Has to live till the call comes.
