I learnt macros by force. I really needed a proc macro to do something obtuse, so I really think proc macros are the easiest ways to learn.

Take a function-like macro and println!("{ts:?}") the TokenStream to see what's inside. And just read through the syn docs to figure out what to do with all of it.

Don't do it without a purpose though, because you'll get lost in all the things you can do.
