It’s too low on the priority list. Rent, bills, food etc. all come first.

I only buy e.g. video games that are exceptionally enjoyable and exceptionally niche or an album on bandcamp of an artist who’s work I particularly enjoy with exceptionally few plays where 1 sale might make a difference, and even then I usually limit any such spend in total to a max of £20 at most, and it’s something I would only spend once a month at most, normally rarer.

As for like, drawings/paintings, I intrinsically see them as having almost zero value and cannot see myself ever paying for one, I would sooner invest in a printer and print something off Google images for a poster than anything else.
