When I was a child I was once reprimanded by my grandfather for not doing something properly. I was rather surprise, since he had just praised my cousin for doing the same thing, but as I found my job was better done. When I mentioned this to my grandfather, he looked at me very seriously, held me in his gaze for a few minutes before saying to me: ,Listen really well. You always have to give YOUR best in whatever you do. Forget what anybody else does, how good or bad they do. Because at the end of your life you don't think of who done what, but of what you have done. If you always strive for your best, you will learn the most but more importantly you will have a full and content life!'
