That's honestly such solid advice. So many people get tripped up confusing wants for actual needs. Makes the whole process way harder than it has to be.
Yeah and what @evas15 said about making that list first is so key. It's like when I grocery shop hungry, I throw in all the junk. But if I have a list of real food I need, I stick to it and save money. Same idea here, stops the impulse stuff.
How do you even tell the difference sometimes when everything feels urgent? Making that separate needs list first stops you from wasting time on stuff that doesn't actually matter. If you skip that step, you end up looking at things you can't afford or don't need. It saves a ton of frustration later.
