Watch out for inflation chipping away at your assets. We've all heard an elderly person describe the purchasing power of a coin in their day. Inflation continues to make today's money worth less in the future. To win the race against time and inflation, learn to invest your money in the right places. A savings account might help you to keep up with inflation; however, to stay ahead of the game you'll want to invest in bonds, stocks, or some other investment that returns above the average rate of inflation (currently 3%-4%).
