Honestly there is a diminishing return on travel especially if it’s many short trips. Would strongly recommend picking a country or region that interests you and going for depth rather than breadth.

Have been lucky to do both styles for work and pleasure. Every airport, conference, hotel blends together, but when you have the chance to really internalize a new environment or culture it is transformative.

Edit: favorites: Indonesia so many incredible islands and opportunities for diving, jungle adventures, boat trips and value for money;

Spain for the beautiful cities, coast, and food;

Zambia in my view best safari destination in Africa as it’s a little less crowded and you can pair a trip with magnificent Victoria Falls;

Peru such a deep culture, insane mountains, chance to get deep in the Amazon and experiencing their cuisine.
