That’s all fine and well, but what if you desire something that can’t be justified as an instrument of work or creativity? What if the thing you want to buy is indefensible?
By that I mean trinkets and jewellery such as expensive mechanical watches, or fancy cars. If you’re really rich it can be yachts or jet planes, but you get the picture; it’s something that makes no sense in proportion to your wealth and income.
The answer to that is very simple.
No.
You need to control yourself and learn to figure out what you’re trying to accomplish, rather than just follow such stupid and financially destructive impulses. Money is precious. It should be seen as a blessing, as something that saves you from terrible things in this world, and who knows what price had to be paid in order for you to get it. I’m not saying you should feel guilty for having money and give it all to poor people, but you should see it as a blessing from God that was given to you in order for you to do something constructive with it. I don’t know what that would be, because I’m not you; it’s always specific. Insulate yourself from harm; be able to actually do what you’re meant to do, since money is fuel for everything else. I also don’t see anything wrong in spending some pre-defined discretionary spending sum on some trinkets that you actually like, as long as you’re not actually depleting the money that’s supposed to be used for constructive things.
Discipline needs to be learned. It’s fine to indulge yourself to a point. Go buy yourself ice cream. It’s not fine to act like a fucking idiot and spend all your money on a car or some other toy. You need to learn to say no to yourself and not act like a petulant child that throws tantrums when it desires some trinket. Your inner child can eat shit.
You need to say no, and you need to obey.
