✔ Get the habit of using consumables entirely before you go to buy new ones. This includes toiletries (like soaps, shampoos, toothpaste, perfumes, colognes, deodorants, etc.) makeup products (like lipsticks, instant glow powders, creams, mascara, nail color, etc.) eatables (like cereals, jams, jelly, chocolates, cookies, chips, etc.) and a lot more things.
