At work, I have a reputation for being the guy who never shuts up about trying to get new people into scuba diving. If there are 2 or more divers at the lunch table I honestly feel a little bad for everybody else. The cost of getting trained and renting or buying all your gear can scare people away, but I would at least strongly recommend that anybody on an island vacation or cruise at least try a "discover Scuba" class. You'll learn everything you need to know to not die by watching a quick video, and working in a pool, then you get to go have an amazing dive in the ocean with an instructor.

Playing an instrument. The challenge of playing successfully a melody will give you more reward than listening to a good one.

Ham radio. It's a lot of fun and has something for everyone. I like the outdoors, so I took my portable gear to a park and operated Parks on the Air today. There are all kinds of digital modes for people who love computers, there's morse code, there's using kites to hoist your antenna, hot air balloons, talking with the space station, etc. All kinds of stuff. If you're the least bit nerdy, it likely has something for you.

Cooking. So many people don't even have the bare minimum ability to throw something together from raw ingredients that's vaguely nutritious, palatable, and won't give anyone food poisoning, so of course start there - it's so much cheaper than ready meals and there are plenty of recipes that are fast if time constraints are why you use ready meals. In fact, a trick I've always used is to cook something that serves 4-6 people, divide the extra into tubs, and freeze it. That's a few nights where making dinner is as quick and simple as defrosting something, maybe boiling some rice or pasta to go with. Do this with a half-dozen meals and you can alternate and not have to cook for weeks.

Beyond that though, learning a little more about flavour and technique, how to season a dish like a pro, some more unusual flavour combinations etc. can add real interest to your diet for very little extra effort, time, or cost. A few cheap herbs and spices can cost less than a single portion of what you're cooking and give you enough to enhance months worth of meals.

Cooking yourself a treat is great therapy. Cooking something a bit fancy for someone makes for a cheap yet heartfelt date night. Cooking a meal your family enjoys is really satisfying. Everyone should learn to cook, just a little.

• making bread
• brewing beer (or making wine or cider, as one prefers)
• repair sewing

I suspect I'd feel the same about welding or smithing, but I haven't tried those (yet).

Mindfulness and Breathwork! Mindfulness is an incredibly valuable practice that can be a game changer for mental health and anxiety. Breathwork goes a long way as a fundamental technique.

There are a variety of free tier apps like InsightTimer that have beginner courses in meditation. Working to create space in your life between things like work and family give you breathing room. Starting to live in the moment allows you to step out of the anxiety of the past and worry of the future.

Drawing! We all start life drawing, scribbling, experimenting etc. But often we drop the activity or don't think were good enough to try. But everyone should take a pencil/pen and paper and just try to draw things, if you want to try and improve quickly look into https://drawabox.com

Pros - It's cheap, easily available to most and often very cathartic.

Cons - if you get into it it takes a lot of time investment to get really good.

tying knots. All you need is a couple of pieces of string to get started. The right knot, well tied, is like a good friend - you can count on it. Shipyard workers sometimes make fun of how inexperienced mariners tie up their boats to a dock with "if you can't tie a knot, tie a lot!?" (full disclosure, I am a sailor).

someone else mentioned sign language - that is also extremely useful sometimes! My wife and I learned it when we learned to SCUBA. We do not have any deaf friends, but sometimes you meet a person who is reliant on sign, and if you can at least spell out some words, 'they are so grateful'.

Two things: chess and piano. I downloaded the chess.com app and play whenever I'm idling for more than a few minutes. Got to a very proficient respectable level in a few months, and it's a ton of fun, endless combinations, no upper limit to how good you can get.

I also bought a cheap keyboard for under $300 and got proficient at it within a few months. Half hour here, twenty minutes there, an hour there. I'm not Chopin or anything and I can barely even play him but again, respectable.

So now if you ever go somewhere and see a chess set or a piano you can be like hey I know what to do with that!

Writing and drawing!

It requires no upfront investment, can be done individually, and it's one of the few arts which is constrained by skill rather than budget. You can write a bestseller novel with just your computer but good luck doing a blockbuster film on your own.

As a car enthusiast, I’m a little biased with this one, but beyond knowing how to change a flat, you should know how to do basic maintenance on your vehicle. Oil changes, brake replacements, etc. Some people are just not interested, which I fully understand, but for those who are, you can save some money with labour costs (and parts in some cases) doing the maintenance yourself.
