Is it worth cancelling your credit cards?

I've made some bad mistakes and want to get rid of any opportunity to use credit. I have 4 credit cards (meijer, amex, chase, discover, all with a balance) and 2 debit cards (5/3, wealthfront). My credit score is sitting at 700 and I don't miss any payments. I know people have said that keeping the cards open with small purchases here and there is a good idea, but the impulse to spend using them would still be present. What do you guys think?
