What are the most valuable skills one can learn in just a few weeks?

Go on a solo trip with strangers if possible to an unknown destinations. Remote areas of your country. The skills you will learn from the locals will be beneficial for the rest of your life.

I have learned so many survival skills on my solo trips. Made a lot of connections which are still getting stronger despite of not being able to see each other often. The hospitality and the happiness that you will find in the small towns and villages are treasures for life.
