Listen to the advice whoever you feel like you connect with. If you like someone's approach, and what they are saying makes sense, go with it.
If there's something about the person or the advice that you just don't like, don't try to apply it directly. You don't want to get into a situation where the you resent or don't follow someone's advice because you don't like the person.
For me, when I was working to get out of debt, I made a budget and stuck to it. And that amount of self control was really hard. One of the things that made it easiest for me was that I put away my credit and debit cards. If I went to the bank and took out $100, I was far less likely to spend it on stuff I didn't need (Starbucks, etc.) than I was if it was as easy as pulling out a credit card. I also built "rewards" into my budget so that when I hit certain milestones I was "allowed" to have a treat.
Also, I called my credit card companies and had them reduce both my interest rates and my limits. And now, I have a rule that I pay off my credit card debt in full each month.
But being out of debt, or mostly out of debt (because I don't count the mortgage), is a WONDERFUL feeling.
