Learning ue with/without course

hello everyone.
I started learning ue4 with youtube videos,some months ago, yet I really feel like I have no idea how to develop
my own game. I dont know how to build with blueprints without a guide,
so what do you think, shall I buy on-line course? it will give any help?

My opinion is that UE4 can be defined as “self-explanatory” in many ways and you do not really need any special course. Just in case if you feel like needing one, I could recommend “Unreal Engine 4: The Complete Beginner’s Course” on udemy.
