When you take a few minutes to care for something, it requires you to step outside yourself. It requires you to change your focus and put it onto the wellbeing of something else.

If you mention the countries Syria, Ukraine, Afghanistan or Venezuela to me, a soft, numb cloud of blissful and most intentional ignorance folds over my consciousness and within milliseconds, I hear no more. Same goes for the phrases, 'world issues,' 'political strategy,' and 'government turmoil.' But no words instantly anesthetize me like the words, 'war,' 'conflict,' 'death toll,' 'budget,' and 'health care.'
