Step 4. Prepare to eventually relocate by researching where and when you may need to. All prior steps will enable this but you must create a plan with benchmarks that will alert you to take action before it is required. A bug out Uhaul is much better then a bug out bag, trust me. This may require a different hemisphere or continent. Successful Step 1 will allow this (see New York State/California circa 2020 for adequate inspiration).
Step 4a. Take a vacation/trip to where you choose from step 4 to ensure that this is where you want to go, when needed. You just may find that it is better to move there (permanently) today. You also need to ensure that your family is going to be on board. If your children suck...today...you probably should have done step 4 some years ago because statistically young people learn more about being a person from their friends than their parents (after entering high school).
Already have one. Mexico. I have visited a half doze times in the last year. Probably one of the more underrated countries to enjoy quality of life. Food and family is very important there like you won't believe.
Where are steps 1-3?
