If you are still gathering your three-month, water or financial supply, don't stop. Continue working on your individual goals. The goals are all posted to the right and you should work at your own pace. You can learn along with the rest of us right now and start your longer-term supply when you are ready.
For longer-term needs, and where permitted, gradually build a supply of food that will last a long time and that you can use to stay alive, such as wheat, white rice, and beans. These items can last 30 years or more when properly packaged and stored in a cool, dry place. A portion of these items may be rotated in your three-month supply.
