Everyone is fighting a battle no one else knows.
Some are more difficult than others but the case is not to debate who has it worse.
It does not impact you negatively to be kind to everyone around you and everyone you meet daily.
Your kindness could make them feel better, change there mood, or even make their day.
You could be the first kind person that they have came into contact with that very same day.
It should also go without saying that even if the person you meet does not reciprocate do not let that get to you. They could just be having a terrible day and don’t let it affect you. You continue giving kindness.
The world would be a better day with kindness.
