Need some Guidance

What’s up guys!

So basically I’m a 19 year old game dev who’s been in the game dev field since I was 9-10 years old. I’ve know about Unreal’s engine since the UDK days and as a kid I would try and try with UDK and 3d and would fail. Hence, i went to 2D gaming where I’ve made my share of games, where most were very successful! But anyways, I acquired UE4 when it finally became free and I was excitecd and still to this day, I don’t know where to start. I’m just so lost in the 3D field and I have knowledge of coding.(Javascript, C++, HTML, little python and java, and Game Maker Language). So it’s not like I’m going in blind here but I’ve seen so many people make indie games with UE4 I was willing to give this another go. I just don’t know where to start and it’s frustrating. I looked everywhere for tutorials but…I just don’t know.
