You know that random day where you're suddenly completely motivated and it's like, "I'm going to train all my animals and register them in all the clubs, and finally name them, and then I'm going to start 3 new breeds, and a project animal."

Yes!

... But inevitably halfway through I lose all motivation and go back to my slacker ways...

This is me always :P

Usually the weeks I finish training earlier in the week I get all bored and feel like I need more animals.

Those days are soo rare for me. And then tend to be like in the middle of the week lol

Yes!  Then I have to remind myself that work and life are going to get REALLY busy in a couple months and I wont be able to keep up. :(
