Agreed with you my friend!
This fits perfectly on me. "If you are not having Fun, You are doing something wrong".
If I ever get into any kind of problems, I faced them with fun & handle the situation very easily. If you do your work with fun then you will not get bore. I always suggest my juniors to do some fun while they are working in the office. So that they can concentrate more on the work when they do.
True, we need to encourage ourselves to do better with fun and love to what we do. If we don't like what we do everyday, we should think on changing it asap!
