Knowing when to give a fuck is an important life skill. So is being creative, resilient, graceful and kind. Many people are awful but not everyone is. Your job is to be one of the good ones. Find and help the others.
The best leg up in this world is love and encouragement, with a parent’s love you can go far. If you have good parents, be thankful, don’t take that shit for granted. If you are a parent, be the best parent possible to your child, especially if your own parents sucked. Because the only way this world can ever be saved, and the only way this world can ever be worth saving, is if we all do better. Stop complaining about whatever nonsense and bullshit. Stop complaining, stop shifting responsibility to others, stop making excuses. Be better by doing better.
