First and nearly always: pay down and stay out of debt. Don’t take on debt unless it’s “productive”. That is, a debt for a home that will grow in value is wise, and a debt to grow a business is even wiser, but a debt for a car loan (while unavoidable, perhaps, sometimes) is not.
I think it’s important for people these days to start weaning themselves from the idea of “financial independence” because at some point our financial system will collapse. It’s all but certain to happen, the only question is “when?” and “how badly and for how long?” I’m not talking Great Depression collapse or even “Great Recession” collapse (as of 2008 and since, for many people), but worse: Zimbabwe, Weimar Republic (Germany during the 1930s, for example) when “currency” becomes essentially worthless. At those times in history it doesn’t matter how much “money” you have.
We need to be able to barter a skill, trade, goods (including food) or whatever else we can produce or acquire to trade for the other things that we can’t or don’t want to produce.
I’ve been in India all this week seeing how “the other 90%” live, and it’s not at all pretty. It’s downright scary. Consider what you could do if money didn’t even exist in our society. Consider what you would do if you were dropped into your environment with no funds, no friends, no family and had to live the rest of your life in that environment and make a go of it. I’m not talking “weekend warrior” stuff here, or “what would I do to get out of the woods?” but “how can I live the rest of my life – from right now – starting from scratch?” Think along those lines and be ready.
Beyond that, I would still recommend doing the necessary things to plan for a financial future: learn about investing in stocks, real estate and even commodities (but don’t try speculating without a lot of cash that you can afford to risk and still sleep at night); start retirement accounts (401k plans if your employer offers one, an IRA if they don’t – and even if they do, and you can afford to put money into that, too); stay out of debt (it’s worth repeating!); but always consider “what if the money goes away? what then?” The collapse may not occur for decades, but it may come out of the blue next week.
It’s when people get smug about “well, I’m all set for life now!” that unexpected disaster occurs.
