Thanks for your response!
I agree to come down with no debt, and that's a part of the 3-year plan. I am pretty good at taking a big task and breaking it down into manageable parts. Even though I am a U.S. citizen, I am not a person who thinks another country should adapt to me, so longing for how things are done here isn't going to be a problem. I've lived overseas before and have done a decent amount of traveling.
Part of my plan is to come spend at least a month in Cozumel within the next 18 months. I will probably make shorter visits there in anticipation of renting somewhere long term. Through my family, I have some connections in the diving community, so if I get in a bind, I have some resources for help. Honestly, there's an outside chance someone will have to take me to the hyperbaric chamber, right? (kidding, but only partially!)
My profession is moving to the cloud, and I'll be able to work from the internet and still learn my U.S. wages. I have a home in Texas that will be paid off soon, and really, I don't have any other debt. I will also bring little with me, as it's just easier to buy things where you land.
