You can't teach an old dog new tricks.
Do you consider yourself to be an adaptive person or set in your ways? The world is constantly changing: it's technology, it's values, it's culture. If you stay stagnant it will pass you by. I believe one of the major traits of all successful people is that they are able to adapt. These people were able to learn how to use the internet even though they didn't grow up with it. They were able accept the fact that people are becoming less conservative. That people aren't trapped in their position in society. That rock and roll music is not made by the devil. Learning to roll with the punches that life throws at you is extremely important. You can never stop evolving, no matter what your age. In fact, probably the only reason that dog in question is old is because he doesn't want to learn a new trick.
