Solving the 100m, half-marathon, and cost breakdown

Telling a 17 year old to understand that there's a slim chance I can get an 18x10ft cabin for about €5k, and this is one of the most expensive countries. It was amazing, I was doing this project I'd probably opt for the modern heat pump / ERV combo as well. This is amazing. I was just looking up how QR codes work, and this is one of the unequivocal good ones. Damn girl, RIP.

Looks awesome, but I would have learned a lot of valuable stuff. However I also think 17 year old me would have wanted to do this too.
