Block time on your calendar for deep work. Eliminate interruptions during deep work time. Learn the pattern of common logical fallacies. Practice finding them in yourself and your interlocutors. Write down your thoughts. Writing things down forces you to structure them. Talk to people you disagree with. Actively challenge your own assumptions and conclusions. When you lose an argument you gain knowledge. When you engage in an argument in good faith (allowing that you could be wrong) you test your assumptions and conclusions.
