Retirement income

My husband and I have a few years to go before we actually retire. In the mean time we are thinking of everything we can to make our retirement as enjoyable as possible. We know we are both very visual and enjoy a "hands on" experience rather than sitting in front of a computer. However having internet access is still a wonderful tool to communicate and keep track of our income and expenses. So while he polishes agates I pour candles and together we find these activities fun!
Because we run these enterprises and have fun doing it I know we have "overhead". Buying and replacing the material and tools to do this is pretty much all of our overhead. We spend about $100 a year in advertising looking for the most inexpensive ways to do it.
If nothing else, we have fun experimenting with ideas for our future. I don't know that we will need the income but we will have something fun to retire to. We know retirement is unpredictable. No one can agree on how much money we need to retire. Some are suggesting a million dollars may not be enough money to retire on. People have lost or have had their retirement savings or greatly reduced by the "Great Recession". Who's to say it won't happen again!
We know for sure we won't have a mortgage. We have other property to live in and is more fun than keeping a house we bought to raise our children in. We don't and will never have credit card debt. After the house is sold we will have only association dues and a couple hundred dollars in property taxes. At the most we will have a car loan.
We just know we won't be content just sitting around reading books and watching TV. We will have to do something to stay interested in life. We love making something from nothing, so we are researching more than anything else right now!
