That you literally can do anything you set your mind to. When society keeps telling you that you need a steady job, and a great career, and a house and all these materialistic things, it’s easy to just give in to that rat race and think that everything outside of that is unrealistic. But you need to focus on what makes you happy! We are living proof that if you want to be location-independent (for whatever reason: travel, family, flexibility etc.), you can make it work. This goes for all goals you might have. You just have to believe in it. The mind is a powerful thing!
