As requested, I’ve looked into some kinds of activities that you can do in your free time. Also with their respective advantages and disvantages.
Well, the first option is to do a two-day diving course. An advantage is, if you like the water and the ocean, but never had the courage to
take this kind of adventure, now it’s your opportunity. But if you are afraid
of diving, that’s a disadvantage.
The second option is a ballroom dancing class. If you like dancing on your free time, but never had time to learn how to, this would be a nice
challenge for you. If you have some skills on dancing, like good interaction with a
partner, good coordination, and resourcefulness, these are advantagens of
taking this course. The bad part is if you're a lazy person, you wouldn’t
take classes for a long time, probably giving up soon, that’s a
disadvantage.
At last we have a long weekend in a foreign capital option. Well, if you're a fan of far distance travels, knowing new places, meeting new people… If you're very
adaptive to new situations, that’s an advantage. On the other hand, If you don’t
like to leave your parents, friends, and pets when you travel alone, and miss all of
them too much, even if it is for a short period of time, that's a disadvantage. You shouldn't travel.
