Yep I can relate. But I have ADHD so that's probably why. I'm fresh at the beginning of the year, but by halfway through, the novelty has worn off and I just am not committed, not motivated, and fall apart.

There are also other factors that you may want to consider tho- halfway through, its been winter (depending on where you are in the world), the weather has been worse than it normally is, the holidays are stressful, finals may have taken their toll, etc.
