Some experts believe that we should force a smile even if we’re angry or sad.
I say that’s BS! You’re emotions are there for a reason. Don’t turn your back on them and certainly don’t suppress them. They are your guidance system. Suppressing them will cause misery, stress and illness.
If you want to change the way you feel, then do it from a mindset change (PSYCH-K), but don’t mess with your emotions.
