Welcome to the world of adulthood!
The first thing you'll notice is that there is no roadmap to adulthood. This is primarily because there is no right way to be an adult! Everyone has different circumstances, different paths, different timelines, and different goals. What worked for your parents may not work for you, and what works for you may not work for your best friend or little brother.
So instead of trying to keep up with everyone else, figure out a path that does work for you. - When you're ready, these resources will be here to help make that path a little less bumpy.
