Seeking Happiness and Laughter

So I have discovered that a lot of us are very fun people. We like to have fun, when we are in the right mood we can create a lot of laughter, we can have a very good time, and of course enter into the "laugh attack" where we cannot stop laughing. This mood, hopefully in a sober condition, allows us to have fun and laugh. It gives us happiness.

The other form of happiness comes from two things: calm/relaxation, and doing something that makes us happy/excited.

The reason I am posting this is because I think I have been in a serious mood for too long, when I go to parties I am not able to tap into that laughter and the fun side of myself, and I lull there. So the question is: How do I tap into that fantastic ability to laugh? How do I tap into that ability for me to change my mood completely and crack jokes, have fun, and laugh like crazy. How do I do that (without drugs of course)? I have done it before, I haven't been able to do it for a long time.

So here is my plan, which you could use for yourself if you are in the same condition:

1. Take note of the items that crack me up. What makes me laugh? What kind of jokes? What kind of humor? WHO makes me laugh? Which people's general everyday personalities crack me up?
2. After taking note of those things, I need to find what turns on my fun side. What kind of environment, items, or people turn it on? What kind of day did I have to be able to tap into the laughter, the jokes, the loud and fun side that I have seen only on occasion?
3. Beyond laughter, what things bring me calm? What things bring me relaxation? Do these items bring me happiness as well?
4. What items excite me? What things put me in a mode of fun excitement?

These are the only things I need to look for. I guess if you know what makes you happy, what makes you excited, what makes you laugh, and what makes you relax, you would be able to tap into those things more often and help release the pressures and the seriousness of the day.

Hopefully this help! I know that I will be paying attention to these things!
