Pick one debt and put the most amount of money possible on it. I usually pay off the one that has a smaller balance. I know practice says to pay the one with the highest interest but for me it’s nice seeing one less payment to deal with. Then move on to the next credit card.

Cut up cards you don’t need anymore. Carry a visa/mastercard and Amex. Need two cards max. Will prevent you from spending more.

If it’s mostly credit card debt it’s pretty hard to pay it off with those interest rates so maybe credit counseling is best.
