A simple and useful piece of personal finance reminder I received recently was to move saved cash from an ordinary savings account to a high yield savings account. Where I am, that instantly changes the interest rate from ~0% interest to ~1.9%.
Of course, a “high yield savings account” is just a fancy name for an account that ensures your money keeps up with inflation. But, if you maintain an emergency fund in your savings account, for example, it is worth finding a savings account that at least ensures you don’t lose money to inflation every year.
Over time, that is worth a lot – literally. :-)
