I feel like the absolute best financial advice I can give someone is: take a Financial Peace University class. Financial Peace was founded by Dave Ramsey. The principles they teach are absolutely doable and fantastic. And Biblical!
I could give you my budget ideas and blah blah blah. Or I can just tell you, find a Financial Peace class and take it. Whether you're fantastic with money and just need a few more pointers or you're crazy in debt or just need actual ways to handle your money better. Find a class and take it!
