This particular post (and form of self-care) will be very short and to the point: be nice to people. By being polite, mindful, gracious to other people, you are causing a ripple effect that will surely come back to you. We all have experienced some unpleasant situations when we are just the innocent bystander caught in someone else's bad day. Take it from Taylor Swift, it's best to shake it off! Give your feelings validation if something hurt you or made you mad and then, do the unthinkable: try to correct them with kindness. I don't mean shake your finger at them, but lead by example.
If a stranger is abrasive towards you, you don't know what they're going through (which doesn't justify their attitude), but, sometimes, you have to just feel compassion for individuals who don't have the harnessed strength you may have. It's actually very sad that they let external affairs inflict and burden their day to such an extent. Turning the other cheek can be one of your most powerful tools. Like attracts like so, do everything it takes to avoid dampening your positive vibrations. No one is deserving or important enough to steal your joy and opportunity to have a great day. My dad has always said, "be a thermostat, not a thermometer" and I think it's great wisdom to put in your back pocket each morning. By being nice to people, we are allowing others to do the same.
Need some bonus inspiration? Watch Disney's Pollyanna. This movie molded me at a very young age and is definitely the most impactful piece of cinema I've seen! I'm completely serious, it will change you.
