Much of what bothers us now, one day, won’t matter. The ability to let things go and live in the present can save us a lot of time. Most of our worries are inaccurate anyway, and holding onto them doesn’t keep bad things from happening. And sometimes holding onto them leads us to actions that worsen the situation.
Murphy’s Law says anything that can go wrong will go wrong. But not all at once, nor necessarily within our lifetime. Some things will go wrong, but it’s also true that many things will go right, including things we didn’t orchestrate ourselves.
Think of worst case scenarios, and try to avoid them the best you can, but don’t dwell on them. Put contingency plans in place to deal with things that go unavoidably wrong, and then get back to living.
