The one thing for sure in life is that it always changes. Embrace the possibilities, ignore the fear (unless ofc you're in a sketchy alley or something, duh)
One of the most important things no one teaches you is resourcefulness. Sometimes if the people around you don't got answers for stuff, you gotta go out and find someone that does. For every problem, there is a solution.
Don't sweat the small stuff. Everything tends to work out in the end.
