Being Happy is that the same as being content?

I was thinking about something. Actually it's about a lesson I learned the hard way. It is how to be content. Being content isn't being happy. But sometimes I would get that mixed up in the way I thought. I would wind up chasing after things that would make me happy and ended up pretty miserable. I guess the reason that I would be miserable is because everything in the world is temporary...therefore, everything only has a temporary happiness. The flip side of that? Since everything is temporary, everything has temporary sadness too--that's a good thing :-). The only true happiness or contentment is found in serving the Lord...that's because those things we do for the Lord and the spiritual blessings He gives to us are all eternal, therefore they have an eternal happiness or contentment. The pursuit of righteousness and holiness will bring contentment.
It's easy to get caught up in pursuing the things in the world. They are easy to see...in fact they are easy to get our hands on right away. The crazy thing about that? The minute I get my hands on those earthly treasures that I thought would make me happy, they tend to disappear in my hands. The happiness they bring might last for a little while, but then I find myself moving onto the next thing. Looking for happiness again.
Matthew 6:33 has been a very important verse in my life. "Seek ye first the kingdom of God and His righteousness and all these other things (what we need) will be added unto you."
My job is to focus in on seeking the things that are found in the kingdom of God--you know, the things of eternal value and seeking His righteousness in my life...when I do this He just takes care of everything else.
