There are very few things that are going to make a bigger difference in your writing than certainty. Certainty, or the state of being certain, means that you do not let other people’s doubts bring you down. Of course, it’s a state that’s difficult to achieve, and you won’t achieve it by “faking it until you make it.” You’ll achieve certainty by focusing on the things you are knowledgeable about. You’ll achieve it by saying things that you know are true. The world needs more certain people. Especially in the last few years, we’ve seen a lot of chaos and uncertainty in the world. It’s your time to be the leader you can be, and to show the world the certainty you have about your ideas.
