Hard work is good, Smart work is better
Hard work will always pay off and is well respected.  Smart work is more important to success.  Smart work also takes hard work and time to do it as well.  It is just that smart work can decrease time in the future if you are willing to put the effort to make a change and learn it.  That also includes putting your ego away and accept the hard work you did may not always be the best way.  Smart work is not about finding the easiest way out.  It is about finding the most effective way to get work done through hard work.
