Good advice, even tho saying "you don't need this" is relative tho. Sure thing, the only things we legitimately NEED is basic needs, the rest is relative and depends on the POV. For example for me, I needed to upgrade my computer recently, maybe other person could have said "you don't really need a better graphic card" but in my POV i really needed it so fuck it, I bought a new one.
It's not money wasted if you buy something you truly need, same thing goes for time. If you enjoy time you spend doing something (like playing games, etc) it's not wasted even though it would feel like it a week later or so.
