There is something to be said about going to school again as an adult. I realised that it brings out some of the nice things in us which we forget as we grow old:
You do not hesitate to admit that you don't know something.
You make mistakes but still keep trying.
You can laugh at yourself with others easily without any hurt.
You prefer to keep things simple.
Finally,
you are not afraid of failing.

Simple principles but so tough to apply in our day to day life - wonder why?
