This is absolutely true as we humans are more a survival instinct base and when we are in the comfort zone too long, this can crumble pretty quickly. I have recently been feeling over anxious over little things that in the past I would not even think about until the last minute as I was working on huge issues to resolve. Now that I am doing well for myself (knock on wood), I feel myself stressing the little things. For example, I have no credit card debt after years of focusing on eliminating it! However, I am bothered by a car loan that I need to pay every month! Your comments have given me some great perspective on the reason now...
