There’s a ton of good tutorials now but personally I think just going through them is a quick way to burn out and get bored. The way I’d suggest doing it is set a goal that is simple (you’re sure people have tackled something similar) like... designing and programming a drunk fish flopping around on the floor. You know, something that’s fun and not a crazy amount of work.
Then chop that task up into smaller bits and get googling! Like... “Godot how to floor” “Godot add animation” “blender make a fish” “how to French kiss” “how to do character stats” you know all the parts that’ll make up a fun and small finished product.
To learn you really have to get your hands in there and move stuff around, type out the code, and chuckle to yourself hysterically when you realize that one drunk fish is only a few lines of code away from having 900 drunk fish flopping all over a scene.
