How Do You Come Upon That Relationship With the Music Industry?

I have the whole song written out, and then i have the u to beat, and then now i need to structure it to make it have a pre chorus, chorus and whatever. I structured it to match the lyrics and whatever. It takes a day. There were some issues with it, and id go back in like a week and a half. And then i fixed it. On my drive back, that was the first time i had listened to my own music back on the highway and enjoyed it to the point where i was like smiling, windows down, doing sat and was amazing.
