Clarity over certainty
Any certainty your mind tries to create about the future is simply a recreation of past memories and experiences, and the future cannot be the same as the past. It will always be different because everything is changing.
Instead of only taking action once you have gained certainty, which is impossible, take action once you have gained clarity on what is most important to you at the deepest level. We often pretend we are confused because we are waiting for certainty, when really at our core, we are crystal clear.
What would become possible if you stopped seeking certainty and relied on clarity instead?
