Re: there's something wrong with me?
You remind me a bit of myself. Let me tell you about myself.
I'm 'late' with a lot of things: I only started to care about the way I looked around 15 years of age, only started to go out a little at 16 (though that was only for a short time, as I didn't enjoy the places I went to), only found my 'main' hobby when I was 16 (sports: defense sports with fitness, narrowed it down to just fitness around 21-22). I only really found out what music I liked around... 18 or something, and I narrowed it down in the next years. Still am. When I was 19 and finished highschool, I still didn't have a clue what I wanted. I started Bioinformatics, because that was the only thing that really caught my interest. There were a lot of things that did interest me, but I couldn't image that they would keep my interest enough for a job. You see, I have a broad interest in things. I like to know a little about a lot. Bioinformatics combines two different subjects that I happened to like.
Now I'm 24 and I've only just some months back (23 at that time) somewhat found out what I really want to do for work; something with visual programming and human anatomy.
The point I'm trying to make is, you could either or both be 'slow' to find out what you really like in life, or have a broad interest in a lot, but nothing in particular. Which is not bad. It's just a problem to find some kind of study/work that fits you.
You could also have a low drive in general. Do you happen to have a spouse, or actively looking for one? I myself don't. I just can't find the time and/or energy to go out... (also, I'm not particularly shy, but I can't get myself to start a conversation with a girl, 'cause I either don't know what to say or I'm afraid that I won't be able to keep the conversation going). That's some sort of lack of drive that I have.
EDIT: I've forgotting to include the most important thing: (I know this all will sound cliché, but I really don't give a damn, because it's true) being able to appreciate the small things in life!
I wasted so much time worrying about what others think of me, like thinking that being seen as a 'strong' person is important. For the last 1,5, 2 years I know that being able to not care about what others think (but, of course, NOT in the sense of not taking care of yourself regarding hygiene, physical exercise, etc.), and to simply enjoy!
Laughing about the smallest things, especially with your friends, is so joyful. I really considered myself happy when I learned that. I can crack up just from reliving a memory of something small that happened that made me and my friends laugh out loud.
Memories of such times are real treasures. I really mean it.
