This may be shit advice, but it may help.
I have a mint laptop and was also linux illiterate when I started. The way I did most of my learning was by googling (or duckduckgo-ing) “How do I [x] linux mint” and reading through stack overflow threads. If this doesn’t return results, (almost) any solution for Debian or Ubuntu will work on Mint.
In general, I just assumed that if I thought the computer could do it, there would be a way to do it.
A really good way to do linux is to play around and break things, but to have a backup you can restore from.
I don’t know about other distros specifically, but Mint comes shipped with Timeshift, which is easily configurable and can be set up to include your home directory. Make a backup on an external drive every now and again so that if you break everything, you only lose a bit of work instead of all of it.
Search engines are your friend. If you want to do something, look it up first (ex/ “How do I [x] on linux”) and read some of the answers. Don’t just go with the first option you see, and if it looks decent but you don’t understand it try looking up the commands it uses to find some documentation.
Learning linux isn’t something you can do as passively as you can with Windows, so take time to really try and learn things you’re looking to do.
And a good rule of thumb is that if you think your system should be able to do something, it probably can.
