Hah, this is very good advice in all hobbies in general, and indeed I doubt many follow it 😅
One thing that I know about myself though is that if I have a thing that I realllly like, I just end up using it more. I have an Italian motorcycle - the performance to price ratio is questionable (even if I'll never ride it to its limits), but damn is it a thing of beauty - when I enter the garage I feel positively emotional. Call me shallow Back to the basses: the ones I have are a necessity (they're what was available locally at the cheapest price point when I needed one, and due to moving countries a few times it was actually just cheaper to buy more), and I like them, but... you know Life is hard, eh?
