answer:Invest as much as possible while you’re young and take risks. There are 2 major factors for building wealth: starting early and taking on risk. If you can start early, the magic of compounding interest could leave you with 2 times (or more) money when you retire than starting later. Risk is the other major component. When you’re young, you have the luxury of taking on much higher risks. If you buy something and it tanks, you can hang onto it for many years while it recovers. Whereas if you buy something when you’re retired and the stock tanks, you may be forced to sell it at a very steep loss to buy your groceries. As far as debt, pay down things with the highest interest rates first. If your rate is really low, you may actually be better off investing that money rather than paying off the low interest loan. It sounds like you live very frugally when possible. That’s an excellent mindset. Try to resist expanding your standard of living, and instead focus on really building your investments up. I.e. try to pretend you never got the raise (or that you got a smaller one than you did) and invest the rest.
