Girls, Guitars, Rules and Birthdays

I turn 25 in five days. I bought a guitar and my fingers already hurt. I quit my tele-marketing job. I accepted another job that I truely feel is something I will do for the rest of my life. Thats a good thing.
The big 2-5. Why is everyone reminding me that I'll be a quarter of a century old? At least my car insurrance will go down a bit. I keep thinking about what has gone on in my life in the past ten years. I was 15 and a freshman in highschool. From then to now, I could write a few books on my experiances. Hell, I could write a ton of books just based on the past five years. Ten years doesn't seem all that long but I wonder if the next 10 years will have just as many experiances. With any luck, there will be more good than bad times ahead of me.
Speaking of luck, things have been turning around for me lately. I started a new job. I have great hours and weekends off. I've been dating a lot. It is amazing at just how many people are really out there if you just take a chance and go looking. I've been maintaining a rule though. No sex unless I am in a comitted relationship. That rule has already worked out in my favor. For example, I was dating this girl a month or so ago. I'll call her "B" for privacy purposes. Well, after taking B to dinner and then back to her place for a movie, we made out for a little bit and that was it. We had a fun evening and I didn't want to just jump in the sack with B. Well, I take that back. I REALLY wanted to jump in the sack with her but I restrained myself due to my rule. She seemed impressed with me when I told her about it and said she felt the same way too. I was for sure I was with the right kind of girl and I couldn't wait to see her again. Two weeks later, I found out that she had a threesome with a girl and a guy. I wasn't too upset about it. I was...proud of myself for keeping my rule and not breaking it. I don't want a woman who does those things. I have nothing against that kind of lifestyle but this is my life and that is not what I am looking for.
Like I said, I've been dating a lot and it had been a lot of fun. I've made a lot of new friends too. I feel like my unfair life is becoming fair again. I'm not happy. I'm never happy. But I can now see that I have the ability to become a happy person once again.
Time will tell though.
In the meantime, I am teaching myself to play the guitar and its been a lot of fun. My fingers on my left hand are very raw though. haha. But playing is fun and I get to tune out from everything else for a while.
