Ask Lemmy

Travel, live abroad if possible, and experience living in a big, culture-rich city. Unfortunately the economic realities of the 2020s are making this increasingly out of reach for many youth, but if you have the resources and opportunity, absolutely go for it. As you get older, responsibilities and lack of energy will likely sap much of your ability/desire to move around as much (this isn't true for everyone, but it's extremely common). Even if traditional travel is impractical for you, there still exists cheaper opportunities for exploration that are a bit off the beaten path, such as the WWOOF program.

Regardless of your situation/location, one thing that basically anyone can do is get involved in a cause. Find something you're passionate about and throw yourself into it. Make sure it's something that you can do in-person and not virtually... as in, there are local groups you can join for this cause, although if there aren't you can always try making one or forming a local chapter of a larger org. With the right networking you'd be surprised how many other people will join you, especially for causes that involve your local community. This is a great way to meet other people, get to know the issues facing your neighborhood/city better, and learn to navigate your local government/NGOs. Again, as you get older responsibilities/exhaustion can make this sort of thing a lot harder.
