Yup, I rarely worry because I’m prepared for a lot of the most likely issues that could come up. We have:
a healthy emergency fund, so we can weather unemployment
food in storage, so we can handle a natural disaster for a least a couple weeks
two cars and flexible work, so we can handle a car going kaput
space heaters, so we can handle the furnace going out in the winter
And so on. The more prepared I am, the less I worry. However, it’s impossible to prepare for everything, so I do worry, but I’m able to make that very infrequent with planning.
