Don’t skimp out on things that separate you from the ground. Shoes, chairs, beds, etc. Those things can affect your posture and bad ones can put you in pain, and you’ll likely be spending a lot of time in them, so it’s worthwhile to spend extra on quality ones. I’d say getting 4 years out of a pair of boots is a steal.

On the subject of boots, I bought a pair of Wolverine leather work boots for about $120 back in the early '00s, and wore them for 10+ years, albeit only during the colder months and casually. The only thing that wore out on them were the insoles.

Gunpla and other mecha model builder, here. 1k Euro could get you anywhere from 4-75 model kits (likely more if you really wanted to stretch it), a sweet airbrush setup plus all the tools you could need, or a few nice display cases to show the finished models off in.

It’s a given that you’re interviewing because you need money. They want to know why else you want the job.
