Travel 24/7, 365 days a year. There is no single more enriching experience than traveling: it takes you out of your comfort zone, makes you learn a ton of stuff about yourself and the world, and you get to see beautiful things in the process.

While traveling, I would take the time to learn every language I come across, and not leave a place until I am fluent: learn Japanese in Japan with Japanese people, Hungarian in Hungary with Hungarian people and so on… Learning a language is challenging, but it is also an outstanding way to get unique insights about the world and different cultures.
