I went through a period in my life where I felt like I wasn't enjoying anything I was doing anymore either. I wasn't enjoying comics that much anymore, or the forum I was posting on, and I had long ago lost any genuine interest in drawing and wildlife. Only since this year has this been slowly turning around again. Part of this turn-around is owed to someone I talked to on-line early this year, lots of chit-chat and we compared our tastes in music too. After talking to her, I found myself more inspired to get out of the house a bit and have fun in general.
These days, something I derive quite a lot of pleasure from is listening to Indonesian pop music, which may sound a bit silly, but perhaps not so much as some others have mentioned listening to music as a source of fun (quite naturally). Also, I'm beginning to SLOWLY develop an enjoyment of my old interests, though I haven't started drawing yet.
So, yes, I can honestly say, after a long period of apathy, I am genuinely having fun, listening bands like Ecoutez!, Maliq N' D'Essentials, and Parkdrive. And some J-Pop, too, again, thanks to my online friend I mentioned earlier.
