Sometimes I start with the beat. Sometimes I can write something down and it takes me a while to figure out how I want to say it or the beat I want to say it to. I definitely like to live the experiences that I cover.
I write a lot. I used to write a lot of poetry when I was younger, write for my school newspapers. Also reading is very important because you need to be on your word game if you want to be a lyricist.
Not to sound egotistic, but I've gotten kind of good at it. It's something that came naturally to me, but my rapping is rooted in my writing.
