I still have a problem with the statement "...make time to find out what you really enjoy". Sure, everybody wants that.
But take the example of running, or writing. Well like many people, I hated running at first, I really did. But I sticked to it because, well maybe it was some kind of challenge I had set to myself. And I got better at it. And I started to enjoy the feeling, to understand the messages from my body.
This is a classic example and I'm sure I'm not the only one to whom that happened. But let's now take the example of writing. I'm no writer, just a casual blogger (at best). I write by periods, but there is something I noticed: when I write often, inspiration and creativity flows more easily, and I tend to enjoy the activity more, while when I'm writing sporadicly, inspiration just doesn't come, and writing becomes a chore.
The opposite works too. I've always loved playing video games. This is something I really enjoyed doing. But you know what? When I turned 20, I decided that I would no longer play on a regular basis because I had better things to do with my life. Now I only play about 20 days a year, during the holidays. And that's it. And I'm happy because while I wasn't playing video games, well I got better at programming, I read Nietzsche, spent some time with friends (all things that I used to enjoy less that playing video games), and learnt how to love these things more than playing games.
Another point I'd like to raise is the fact that some things are more difficult to appreciate than others. Take wine for instance. Very few people like wine when they first try it, but when you get better at distinguishing the flavors, it is something amazing. The same goes with coffee (I mean coffee without sugar, cream, and other spoilers). Same with Jazz or Classic music. You have to learn how to appreciate these things.
I guess what I'm trying to say is: don't trust your first impression. Or the second. Or the third. You can only know what you really enjoy if you try different things, and stick to them long enough.
