Daily driving beater cars. I have the tools, knowledge, shop space, and time to buy just about anything without getting scammed and get it back on the road. But if you don't have those things, buying a beater car can be a good way to create a lot of very expensive and difficult problems for yourself.
Daily driving Linux. I have the skills, knowledge, and time to deal with the little inconveniences that inevitably pop up from time to time. Many people do not.
Cooking from scratch every day. It requires a lot of knowledge, and time management to
- Make sure there's always something on hand to eat
- Make the most of what you've bought without wasting anything
My whole day-to-day schedule revolves around what I have, what I need to eat before it goes bad, and what I have time to cook. Many people aren't able to plan their whole lives around prep, cooking, and storage of food.
Hiking, camping, hunting, fishing. If you don't already know for sure you like these things, you're very likely to not enjoy them. In my experience, everyone who likes these things grew up liking them. I've never met anyone who grew up without them and decided later they did. I've met plenty of people who thought they'd enjoy these activities, only to find out half way through their first or second trip they actually hate everything about them and want to go home right NOW.
