How to prevent myself from buying things I don't want
To me the key is a budget.  Each month, before it begins, decide on what to spend on each dollar that you earn.  Money should be allotted for normal expenses such as housing, food, transportation, and utilities. If you have any consumer debt that should be a priority.  Extra money should go to eliminate that debt. There should be money allotted to savings goals (such as retirement, home down payment, or vacation home).  Also there should be money set aside for clothing and giving.  Giving is an important part and often overlooked part of wealth creation.   Somewhere in there you should also give yourself a bit of free money.  For example one of the things I spend my free money on is coffee.  I buy freshly ground coffee from a really good supplier.  It is a bit expensive, but that is okay as it does not preclude me from meeting other goals. If you still have money left after all of that increase your giving some, your savings some, and your free money some.  You can then spend that money without guilt. If your budget includes $100 of free money per month, and you want something that costs $1000, save up the $1,000 and then buy it.  Do not borrow to buy free money stuff!   Doing those sorts of things will make you weigh purchasing decisions very carefully. If you find that you cannot stick to a budget, you should enlist a friend to be your accountability partner.  They have to be very good with money.
