What do you spend the most money on when it comes to personal use?

Long story short, I'm trying to open a few online stores because for the most part most self made forms of income start slow so if I just have one then I will just be waiting there wasting time waiting to sell products when I can speed up the income if I don't just limit myself to one category of products and I open more than one and maybe speed up the income but I have to know what I want manufactured before really doing anything so what category do people spend their money on, I'm personally asking y'all, what do y'all buy yourself the most? Clothing? Self care products?

Im opening one for custom shoes but I also wanna sell clothes, would it be better if I mixed the clothing one with the shoes or just make another for the clothes and keep the custom shoes and clothing separate? Lmk opinions, for this one your opinions are indeed more important than my own.
