You’ll observe the theme of your thoughts (light/dark, pessimistic/optimistic). You’ll notice their flavour – maybe it’s worry, regret, anger, jealousy, fear, insecurity, sadness. Maybe they’re ‘less than’ narratives, like “I can’t” or “I’m not good enough, or smart enough” or “I’ll fail” or people will laugh at me – which are all very common, (and bloody un-fun) programs.
