One practical way is to cut down unnecessary spendings. Find a financial institution which can refinance your bad debt and can give you a good payment scheme.
I'm in bad debt and i've found in the past that to help it along, saving up every penny can make a difference, so i just put it into a piggy bank and take it to my actual bank at the end of the month. It really helps.
What really helps is not to get into debt in the first place. It sounds silly, but if you get yourself out of debt, just don't try and fall back into it. I.e. don't use credit cards or get loands out, its just too easy to fall back down again!
