Practice road-rage roll playing. People are NUTS! It's hard to imagine how you'll react when someone gets aggressive with you. Let's practice staying calm when someone is shouting and in your face.
Other peoples’ expectations are the guard rails on the road. They keep you safe and guide you he way - literally. They keep you from driving off a cliff. So if you want to be safe, and if you do that’s great, stay within the guardrails. But if you want to fly, you’re gonna have to run right over them.
Okay algebra and geometry but other than that, spend time practicing addition and subtraction, multiplication and division. That’s 99% of the math you’ll need to know if you’re not going to be an engineer, etc.
Be yourself. No need to pretend to like something the crowd is doing. Half of them are probably just as unenthused as you are but are afraid to say so.
Look into a class for meditation for kids. I read an article on a Baltimore elementary school that replaced detention with meditation and had amazing success.
Having an opinion is not the same thing as having an informed opinion.
If you don't know enough about a subject to speak intelligently about it, keep quiet and educate yourself.
My dad was a Marine. He enlisted at 18 with his buddies during he Korean War. He was never a "typical" Marine, always a gentle spirit and rarely spoke about his days in Korea.
One carry-over was kind of a little inside joke he had with his buddies in the war: They used the expression "Semper Fi" sarcastically, in the opposite way it's meant. When they said it to each other it meant "I got mine, you're on your own. Fend for yourself." We always used to joke about it too when little things happened like there was no more milk for the cereal, "Semper Fi." Of course the irony is that my dad and his Marine buddies were the very definition of faithful when it came to the big stuff. They just liked to joke about the little stuff.
Still use it jokingly that way to this day.
Start saving money early. Save as much as you can.
There are plenty of things worth spending your money on, but be mindful about your money - Don’t p*ss it away.
When you’re in a disagreement with someone or feel you’ve been wronged, it’s helpful to remember who the other person is. Are they someone of integrity? (If they’re your friend I bet they are.)
Remember then, that even though they may have done something to hurt you, they were likely believed their actions were doing (or at least trying to do) the right thing.
People sometimes get it wrong. Or they don’t have all the facts. Or their mind is just somewhere else.
The pain you may feel from a perceived slight is probably not intentional, but even if it is, try to forgive and let it go. We’re all just doing the best we can.
Speak up when it’s called for: Fight injustice, stand up for others, etc. but shut the F up if you’re thinking about offering an unsolicited opinion or advice about anything you’re not personally an expert in.
Sometimes it just takes a while to catch on. I had to watch Game of thrones 3 or 4 times before I could keep track of all the characters and subplots. Record your lectures so you can replay them a few times.
