It's true that I'd be breaking into my emergency stash. Since I don't want that, I'd thus have to pause breaking down the principal of the mortgage for a couple of months.
Thing is, everything feels a bit distant currently. My calculations show that the interest-only part of the principal could be killed in 13 years. So when I started three months ago, I was in this zone where I was doing the calculations, changing its parameters, etc. and I really felt on top of it. Now that 13 years seems awfully far away.
The trip will be done on the cheap, I've got a friend there and we can stay over at his place. As Olivia says, the land is cheap, too. The laptop will easily provide months of fun. Knowing me, I'd probably spend lots of time looking for a sticker to put on it, getting to know the ins and outs, talk with people on the Apple forums about it, etc. It'll be child-like fun.
I read and re-read the article MsSindy points to -- apparently I'm mentally not in the place which MMM mentions. Where I'm able to reprogram myself off of the laptop.
I checked out the difference between spending and not spending. If I spend that 2,000 now, it'll cost me an additional 1800!! euros in extra interest. Oh my... that's a lot of money. That did make me think twice about diverting funds for the laptop, that was actually meant for the principal. Here's hoping that future price tag will seem high enough to not do mindless spending.
The trip, I might be able to make it cheaper. But realistically, it'll still cost 1000. Meeting my old friends there will be absolutely awesome. Perhaps I could pay that by selling some old stuff, saving a bit extra, etc.
