Reddit reviews Pocket Guide to Emergency Bicycle Repair (PVC Pocket Guides)

What keeps you from trying these things on your own?

Do you live in Canada? Mountain Equipment Co-op offers basic maintenance classes. Drop in, pay a couple of bucks (or sometimes for free), and learn about tire repair one day, brake adjustment the next, etc. Similar stores in other countries, as well as some bike shops, offer brief workshops or full courses.

Or you can just try to learn by doing. Pick a YouTube video and follow it to get hands-on experience. Once you've done a repair four or five times it becomes second nature, no longer something mysterious and daunting. And they say that once you do something seven times it becomes part of your knowledge for life.

You can also follow a book on basic bicycle repair, doing the repairs chapter by chapter.

If you have a friend with knowledge and a bike repair stand, go get your hands on your bike and start doing adjustments and mock repairs.

It's not a bad idea to have a small guide with you, since you will likely forget some (or all) steps. But it's still important to familiarize yourself with the parts and procedures before you go out, as you might not want to spend hours learning how to do a repair for the first time while in a torrential downpour, or as night falls, with a gajillion mosquitoes biting you.

Some guides are available as apps or downloads for a smartphone, but these entail extra complications like making sure you don't run out of battery charge, and keeping your phone from getting all greasy, etc.

If you are not self-sufficient when doing an activity like solo touring, which requires a level of self-sufficiency, you are inviting trouble. Trouble may just become the next adventure (e.g. having to camp out for two days in Alberta or walk 30 miles in Manitoba, or being more vulnerable to obnoxious or dangerous people, all because you can't repair your bike in good time)... if that's what you're into.
