I would like to write my own song but i have 0 clue where to start or what to do. where should I start first? how do I decide on a good time/melody/rhythm? sorry i'm  asking so many questions, I'm just really confused
i have good and bad news. the good news is, you can definitely write anything and everything you ever wanted to write. The bad news, and maybe this won't apply to you, but, it took me many many many years to figure out these writing questions you mentioned. and this was after i had already had many many many years of general musical experience. so the writing thing was still many years on top of that. But i am quite sure that most people are not anywhere near as..... difficult... as i am
