Get rich quick schemes do not work. Many seniors who thought there was a deal to make money quick lost all their life's savings.
Investing in the long-term is the only sure way to make money.
Putting away 15 to 20% of your earnings is a good way to save for your retirement and rainy day.
The 'classic' investment advice holds true;
a. never put all your eggs in one basket
b. save on a regular basis - preferably every month
c. diversify your investments
d. as you get closer to retirement, increase your ratio in bonds vs equities
e. never try to time the stock market; it can't be done
f. buy low and sell high
