It sounds like you got a mindset problem. That should be fixed first. Dave Ramsay's pretty good at helping people like you. Just search for his youtube channel where he takes radio calls. It's fun to watch him yell at people who are being dopes. Once you start to predict what he's about to say to these morons, you'll know you've got the right mindset.

If you cannot stand Dave, there are a bunch of books out there about personal finance and the mindset you need. "The Millionaire Next Door" is probably the best book for getting mad at hyperconsumers.

Finally, once you've got the right mindset, next it's time to learn specifics. I would head over to the https://www.reddit.com/r/personalfinance/ sub, and check out their wiki. It's condensed enough to get through rather quickly, but specific enough that you will be better than 90% of Americans if you spend a few hours really digging into it.
