This could be any info or advice that you think is important as far as investments, credit, saving money, etc.
I'll try to keep a complex answer as simple as possible but this would be the basic recommendation that would hold true for anyone, at any age.
1. Learn to live on a cash only basis for at least 2 years before considering ANY type of credit. This includes creating and living within a budget, and learning to prioritize your spending.
2. Within that time, learn to put away savings. At least $50 a month should go into an account for emergencies (like when your car breaks). If you have a family, you need a bigger emergency account. Ideally it should have about 2-3 mos of your living expenses in it or more (you can keep this in a money market or CD account to keep it available but get a higher interest rate on it).
3. Also you should work as quickly as possible towards putting away the maximum you can towards your retirement. The vast majority of Americans are completely in the dark as to how much money they will need to retire and many, many will end up living in poverty and/or unable to ever retire. Starting this savings as early as possible is a big advantage.
This means funding a Roth or Traditional IRA account to the maximum each year (for your spouse to if you have one) AND contributing at least up to the maximum match your employer offers in your plan at work. Better to max this too.
4. When you are ready to acquire credit, learn to manage it too and to use debt as little as possible, and only to buy things that are truly important and otherwise tough to get, like a house. You can finance a car, but you will be a lot more secure financially if your car is NOT a major part of your monthly expenses. It is possible to buy a car with cash, you just aren't likely to have as nice a ride. At least not in your early years. However patience at that point carries big rewards. Let your friends have an $800 mo payment, you'd rather be rich.
5. Don't forget that insurance is important too. Yeah, if you're single and haven't got kids, your need isn't that critical but there are advantages to buying at least some permanent (otherwise known as whole life or universal life) while you are still young. First of all, it will be a lot cheaper, and secondly, as you age odds are your health will grow to be less than perfect. People with imperfect health pay higher rates or could even end up uninsurable, so buying young protects your insurance rates.
A permanent policy that you've had long enough to build up a fat cash value also offers an extra safety net for money, and can even become a tax-free source of money at retirement age or for your kids' educational costs.
6. Cover higher insurance needs with term. Term doesn't build a cash value but is meant for temporary needs, such as the period of time you are responsible for your kids. For these reasons, it costs a lot less so you can really buy as much as you need.
7. If your employer offers disability income insurance, jump on it. It's cheap that way (and expensive if you buy on your own) and if you ever can't work for an extended period (and most people will have a period in their life when this is true), it will cover the lion's share of your missing income. I can't emphasize enough how huge this protection can be.
8. Likewise review your auto, homeowner's or renter's coverage periodically to insure they are meeting your needs.
9. Once you have the basic habits in place, you can begin to put away more money to invest for wealth accumulation. Sit down with a good financial planner and have them help you define your personal goals and build the plan to make them happen.
