Sometimes, we run into strings of bad luck, and its not the worst idea to take a step back and away from the hobby, to take a little break. Hobbies are supposed to be fun, and when they're nothing but disheartening, frustrating, or expensive, they kinda lose the point. Taking a break gives you a chance to come back to the hobby in a few months, years, whenever, with a fresh start, a fresh mind, and it gives you time to decide what you really like about it. Often, we get a tank, enjoy setting it up, enjoy the fish, and somewhere... stop enjoying it, but its there, and we keep going at it, without the joy anymore. Stepping back can bring the joy back when we return.
And, sometimes, the bad luck is really our own fault -- especially with this hobby. Its easy to get in over your head, to have twenty three tanks, when we really should only have one. You don't realise it, its like that boiled frog, you just somehow got to the point where you're doing too much, not enjoying it, and no longer putting in the time and dedication to doing it that you should.
So, take a break -- keep a tank if you want, just to enjoy, or don't, and come back to the hobby down the road.
