Yeah, despite how I come across here and to others, I'm a pretty serious person. I'd place myself at about the 75th percentile.
I take life seriously. I have a strong need to direct, control, and make sense of my life and the world around me. It's hard for me to 'play just to play.' But I'm also not a buzzkill--that seriousness is mostly internal--and I'm definitely not depressed.
I kinda feel that most everything I do is a 'tactic,' that it must have some deeper meaning, relevance, or motivation. I can play around but I can't help but tie it back to a goal--lightening the mood, easing tension, bonding, presenting myself as 'nonthreatening' so that people open up, personal growth, expressing myself--and so I think that it doesn't count.
A psychologist once told me that, since I'm goal-oriented, that I ought to make play and relaxation a goal. It kinda works.
I define a "serious person" the same way that @SilkRoad does: someone who takes life seriously, takes issues seriously, and tends towards serious conversation topics. In which case, yes, I am definitely a serious person. In terms of what my motivations are, for how I live, why I live, how I interact with people and why, I'm serious 99% of the time. When I'm not serious -- as so many others have said -- it's to give myself a break. I'd go nuts if I didn't have lighthearted fun on a regular basis.
I used to be even worse about this; couldn't make self-deprecating jokes, got offended whenever anyone teased me. I'm getting better now, as a survival mechanism.
when i try to be i usually end up making jokes and laughing. i try to talk politics the other night it end up being about something different mostly because i started thinking the other person was an idiot and i wasn't gonna change their mind. or i get scared and lot of times people will ask if i'm joking but i'm not and i'll say yeah i am because i don't want them to know.
Do you think of yourself as a serious person? How would you define a "serious person"?
No, not really. I would not of course say I am always joking...but I can move very quickly between being serious and being funny. One of my favourite types of humour is a style where it isn't obvious if you are joking. Your audience has to guess, which makes you more mysterious - or infuriating - to them. I also like to treat the subjects people take most seriously, because nothing should be sacred.
I think having both a sense of humour, and the ability to appreciate it in others, are among the important traits a person can have. Humour can add light to the dullest, most boring subject imaginable. Obviously, you need to be able to take back what you give out, and that is something many people, myself included, could probably work on.
Probably the most important thing is not to give a shit. Thankfully I possess that trait more and more every day.
