Worry is such a weird thing when you are not mindful. Just the concept of worry as ‘suffering your imagination’ has turned things around for me a little. I have to worry some because I am responsible for taking care of a family AND run a business that pays my bills and those of our employees. Worry is acknowledging risk with takes on an important dynamic as a business owner.
Other than that, I can go through a couple mental cycles ruminating the risk and then be content that I have it in context. Then a little mindfulness to stop suffering my imagination.
Besides that, when things go really bad and I am worrying about the future, I think back to all the other world ending crises I have faced that didn’t end the world.
