Write persuasive blog articles. Have deep conversations with friends & family. Study neuroscience classes. Over the decades we can become what Scott Adams calls a Master Persuader [read his awesome book on persuasion, Trump, and why humans are not rational].
Emotions are sets of specific bodily sensations [link]. Once they manifest, they are reinforced by loops of thoughts about them. So when you want to easily get rid of an emotion (e.g. loneliness or anger or self-doubt) you can sit down, find that emotion in your body, and pay close attention to it. This breaks the rumination cycle (because you aren’t thinking) and reinforces your self-awareness (because you find emotion-driving bodily sensations => understand that your self-doubt is merely an itch). I can dismiss negative emotions in 30 sec — 5 min. They just vanish.
