The definition of dedication is:  the quality of being devoted or committed to something.  It means to not give up even when times get tough.  Be committed to see things through to the end.  It doesn’t mean not to know when it is time to end it.  There is an end to everything in life and a person should know when that time has come.  But too many of us are ready to call it quits before we have truly seen it through to the end.  We don’t follow through on things we start.  Having enthusiasm for the things you do in life is a necessity to be happy and content.
