You can get into big trouble (with school and the law) even by fake / joke threats of violence (bomb threat, etc.)
No jokes or pranks that have anything to do with violence.
When you see someone in military uniform, thank them for their service. Hold the door open for them, etc. If they are behind you in line at Starbucks, pay for their coffee. At the very least, look them in the eye and smile - they’ve made a tremendous sacrifice and you should acknowledge that.
Always clean from clean to dirty. Wash glassware first, greasy dishes last. Sink and tub first, then toilet. Then floor. Top-to bottom is another general rule.
At the start of a day / project / interview / date / etc. Do this one simple thing: State your intention. How do you want to carry yourself? What is the goal for the outcome? Just take a moment to imagine how you want to behave, react, appear, etc. What impression do you want to leave with the people you interact with? Of those things that are in your control, what outcome would make you proud?
Great article about teaching young kids how to do better than “I’m sorry” when they’ve caused another child pain. https://offspring.lifehacker.com/what-to-say-to-little-kids-instead-of-say-sorry-1819288365?fbclid=IwAR0bKgo60isKj6a5D2s3cs1leWCIyK9TXTBK62upV9U1S_bR0otfJndwg_k
Sometimes you’ll be in the wrong side of history. When you discover you’re wrong, move to the right side of history. When I first started training as a nurse it was the early 1990’s. HIV/$@!#% was pretty new. I remember telling my fellow student I would double glove and take any “over the top” precautions I wanted to. That was my fear and ignorance talking. Amazing how cozy self-righteousness makes you feel. I was wrong. Always look at the issue through the lens of humanity.
Date all kinds but marry someone who loves you for who you are, with whom you feel most yourself. Someone who will encourage you to grow more into the person you want to be. (And be good at encouraging them to do same.) Never fear or stifle each other’s growth. Celebrate it. Support it. Encourage it.
Never post a pic to social media that you wouldn't want Grandma to see. NEVER send or ask to receive naked pictures.
It's tacky, gross, illegal and not worth it. Even if "everyone does it". It's rude and disrespectful.
