I generally feel a sense of relief more than excitement, so I wouldn't say that's unusual at all. As strange as it sounds, I was almost glad to have another loan (investing ~3x more than my car payment, which is at a lower rate than my mortgage anyway) just so I'd have something else to pay off. Given that it's costing me less than my house to finance, I shouldn't be in such a rush to pay it off, but I will anyway.
What motivates me now is watching my balances climb. I will let my checking account float up to $2-3k higher than what I consider my minimum desired balance, then send a lump sum off somewhere (investment, loan, etc) and then let it build back up again. Every once in a while I'll check my 401k and stock plan to update YNAB, but I try not to watch those too much. Bank accounts are directly affected by my behavior (instead of the stock market, lol), so those ones are more fun and less stressful to keep a constant eye on.
