What is the best way of avoiding overdraft fees?

Not writing checks for more than you have in your account.

Don't buy anything that you cannot afford.

If the overdraft fees are from insufficient funds, then you should set up automatic overdraft from a savings account. If the fee is assessed from overdrafting from another account to pay withdrawals, then you would have to access online banking to your account and do the transfer manually. Now, most financial institutions provide an email notification if one's balance goes below a predetermined balance.

Well i actually keep all of that in my mind, honestly i do.
I don't keep a checkbook log, i know what is my bottom line at all times, even when i let my woman have money, but i don't let her have access to the account.
I know that my piss off quite a few women, but i give her money whenever she wants it, i am just the better person that can keep track of these things, she couldn't even keep track of her car payments before i met her.
Trust me she is spoiled by me.

Spend less than you earn and build up a cushion so you don't go overdrawn.

Get a second or third job, build your savings. Keep a big chunk of it in ordinary checking as a cash cushion.
