Money that's squirreled away in savings accounts usually accumulates interest at a set percentage rate. The longer your money remains in the savings account, the more interest you accumulate. Thus, it's in your advantage to start saving as soon as you possibly can. Even if you're only able to contribute a tiny amount to your savings each month when you're in your twenties, do so. Relatively small amounts of cash left in interest-yielding accounts for long periods of time can eventually accumulate to several times their initial value.
