This may be because I'm not as serious a fishkeeper anymore as many peeps here...
I wonder if you get the dream job with fish and suddenly because YOU have to do it, it's no longer fun. Like working in a public aquarium, after a while, maybe you'll get so tired of taking care of fish all day long, you won't even want a tank at home. You suddenly realize, hey I'm spending my life cleaning up fish poo?.
I know a few peeps here could answer that since I know at least one poster ( Zoodiver) works at a public aquarium and I'm sure there are more.
This is off topic, but when I started to train in massage, I liked it and now I can hardly stand it and I dread practice each time. I activiely hate it and I don't know what to do because it's currently my best way of earning money and I kinda need that unless I want to live in affortable housing for life. I'm now dammed if I do and dammed if I don't.
Same thing happens when I work hard on my portfolio, I start to dislike drawing, though I really want to get a job with it. And there's no way you can unless you present a pro looking portfolio, which is really tough since mine got stolen and I lost about a years' worth of work. I keep thinking, it's my dream job but what if I really start to hate it like massage when I have to work on something intensely with a deadline.
Just something to think about.
