Yes, of course. If your employer matches contributions to your retirement plan, take advantage of that perk. Invest in a diversified portfolio of stocks and bonds and consider being a contrarian when the market plunges or rockets higher. If you have the risk appetite and want some sizzle on your steak, allocate a small portion of your portfolio to more aggressive strategies and investments (after doing your research and due diligence, of course). Save on a regular basis to buy a house and keep the down payment in a savings account or other relatively risk-free investment.
