So yeah. Who's the most important person in thy life? I'll give thee some space to answer.... (don't write on thy screen)
....well, if thou paid any attention whatsoever to the title, thou wouldst certainly have answered "Me!" Now, what do we as humans typically do with people who are important in our lives? (that question was more rhetorical - I'm going to answer it myself right now) We get to know the person better.
There are tons of different levels of self-knowledge and self-awareness that it's hard to know where to begin. Anyway, something that I've come to realize after long periods of stress and then lack thereof, is that the latter often comes from self-knowledge. Essentially, you have to know what you want, because only then can you have a chance of getting it. (I'm kinda wondering if it's proper to use "you" for referring to people in general... French uses "on" which conjugates like "he" and means "we"... hrmm.... this is a toughy... leave a comment if you've studied old languages)
Now, this will sound really dumb, but (going by the earlier logic) the best way to get to know somebody is to talk to him or her. Thus, I am suggesting with 100% seriousness that thee set aside some time, specifically designated to learning about the wonderful and amazing person that thou art. (teehee, i'm loving the thou and thee and thy and..... yeah)
There are a few ways to do this, although they are all basically the same thing. I'm almost suggesting a kind of self-meditation, except to keep things casual, with this person thou probably doesn't know very much about (although thou hast probably seen a him or her quite a lot) thou shouldst just stick to normal conversation. Naturally, thou'll want to be alone with thyself, because intimate conversations are not normally something had when other people are around.
I've found that the best way to be alone with yourself is to go for a walk. Snow is great for this, as the coldness is isolating. Once thou'rt (does that work?) alone with thyself, just start talking. Hold an entire conversation with thyself, however thou wantst. If this seems weird... well...
...based on the standards of today's society, it is weird, so accept that and get back to the conversation. Ask thyself what thee wantst to accomplish, and try to understand what things thou art basing thy happiness on. Re-evaluate these values - is this what thou wantst to base everything off of?
The more thou talkst to thyself, the easier it will become and the more thou willst be able to learn. It is healthy (in my opinion) to have regular conversations with yourself. I do it, and I find myself to generally be extremely happy. Even when I'm not, I'm still hanging out with one of my best friends, and that makes up for it. =D
