No thanks

I was reading an interesting though recently.  The premise of it was this: negative, entitled, sour people are not thankful, conversely, joyful/happy people are thankful.  Thankfulness is the crux of being joyful.  This makes sense to me.  I am not a extremely negative person in most respects (I am in some I know), but I try to see the positive. One of my co-workers is always complaining of his job and isn't happy in it.  We have very similar jobs and work for the same guy.  I on the other hand had some rough experiences working for bigger corporations and I am very thankful for my job.  I thank my boss (and God) still (even though it's been over a year I've been with him).  This job has been has been a huge blessing to me and exceeded my expectations in so many ways.  I am happy to be at work and do what I do and work for who I work for.  The only thing that is different from me and my friend is that I am thankful because of where I have been and what I have experienced.  He is not thankful, and from it he feels bitter towards our Boss.  This is one simple example, but it's a real life lesson for me because I understand this on a personal level it helps me to see it's value on a greater plane.  I have made it my goal to try to think of one thing a day I am thankful for, however simple it may be, and try to thank those involved and thank God.  I hope that I in-turn will become more joyful.  Maybe even I can be as brave as to try to incorporate this into my marriage.  As hard as I have it, or think that I have it, there are still things I am thankful for in my marriage and I need to try to express that and hopefully that will help me have more joy there as well.
