Key Points:
Make automated contributions from your paycheck to stick to a consistent saving strategy. Yes, the market can fluctuate, but it's long-term growth that matters. Stash the money then let it go, as markets generally trend up over the long-term.
Consider the Rule of 72, a simplified formula that calculates how long it'll take for an investment to double in value. If you earn roughly 7% annual growth, your money will double about every 10 years. This type of yield typically requires a growth focus, but the point is that compound growth―especially inside a tax-advantaged account like a 401(k) or IRA―is a powerful thing and it's never too late to start saving for retirement.
