Prioritize having experiences over having possessions. I spent all my money as a teen going to concerts and music festivals and have zero regrets.
Treat your friends well. A decade from now, it'll be a lot harder to make new ones, especially if you haven't maintained the friendships you had when you were younger. At the same time, friendships don't always last forever, and people change; don't keep pouring energy into someone who's pulling away.
I use the bullet journal method, the original described by Carrol in his books. One of the core strengths of it is that it still works if you get distracted and don't do it for a couple months — you can jump right back in, because there's no setup and no maintenance required beyond actually using the method.
IDK about "rated higher" but I love Jet Li's The One
There's exactly 127 universes in the multiverse. Why? Never discussed. And if one version of you kills another, every other version gets that much stronger. So Jet Li plays both the hero and the villain as well as an assortment of the villain's victims. Jason Statham is in it too, as the hotheaded junior partner multiverse cop out to bring the villain down.
Weird guns! Weird tech! A prison universe! Super powered martial arts! A climactic fight in a foundry where you can tell the hero from the villain by the color of their shirt! Man I love this movie!
Civ 2 was such an improvement over the first one. I remember both playing and baking mods for it after I exhausted the base game. My second favorite in the series.
From where I'm sitting on my way out the door I can grab a backpack full of toiletries, two pocketknives, several layers of clothing, toilet paper, and a waterbottle. If I go out the back door instead of the front, the backdoor being technically closer, I will be able to fill the bottle, pickup a saucepan and whetstone and lighter, grab a big canister of trailmix I made yesterday and a half-empty box of granola bars and box of salt, and snag a shovel and some offset loppers which will be helpful in making a shelter when I get to the wilderness. No rope along the way but I'll grab the 50ft outdoor extension cord to use instead.
I'm an Eagle Scout and can probably survive with that kit until I catch an infectious disease or winter comes, though I'd really rather have a hatchet and rope. I'd be pretty miserable after the first three days, though.
