This!

If you have time off, do something risky that you wouldn't do normally. Why? Because soon enough you'll likely be back in the normal swing of things and unable to take that risk.

Examples:

Work on a farm

Do the Appalachian trail (or similar)

Take the train across Australia

Learn to ride a motorcycle

Learn to play guitar

Etc Etc

I worked on an organic farm this past year for two weeks (through WWOOF) and it was probably the best two weeks of the year for me. It really opened my eyes to how food is produced and just how much humans have changed the landscape of the planet - well worth the effort

I spent 6 months at home and abroad travelling and WWOOFed for 3 weeks of it. Those 3 weeks had the biggest impact and resonate through my life even today, years later.

Take the train across Australia

Learn to ride a motorcycle

Learn to play guitar

Are these risky endeavors?

I take your point. Maybe "difficult" or "alien" would have been better adjectives.
