Making low 5 figure £ and don't really know what to spend it on. A lot of things people are listing I don't buy not because I couldn't afford it, but it doesn't seem worth it.

I could probably afford most things listed in the comments here, but my main reaction to most of them is why would I want to? Doesn't seem worth it to me.

Never learnt to drive because I couldn't afford it. Now I probably could afford it. At a push even around £500/month exploitative loan used by multiple people I know, would only cause minor financial issues. But I don't want it. My bike is doing fine.

Wtf do you spend money on when you are doing fine and happy as you are with £100s extra a month than you know what to do with, despite earning only a bit over minimum wage?

Only thing I can really think of is save it and eventually pay off the mortgage early then work part time.
