The best way to piss off the world is to waste its time. Think about your fellow man, and don't waste their time. Don't turn left across traffic during rush hour. Don't take 25 items into the 10 items or less lane and pay with a check. Don't ask a question when you came in late.
We spend massive amounts of time and money eating cheap food at awful places. Just learn to cook. It doesn't have to be much, but learn and keep learning. You'll save money, be healthier, and make a better family foundation. Get a rice cooker, a skillet, and a pot. Eat well!
By listening to someone you give them power. Do this. Make everyone around you more powerful. And teach them to do the same. If we work to make everyone powerful, we rapidly reduce the suffering in the world. Give everyone power, and ask them to give it back to you.
The internet is filled with trolls. Don't feed them. Interact with all like a civilized human, teach, empathize, and communicate. But when they start to look like a troll? Don't feed them. Starve them.
If you don't know about the world, you don't know how you fit into it. You need to understand it before you can make appropriate decisions about how you interact with it. You don't have to stay here, but you need to know where you started and where you're going. Know the world.
