My ideas always come randomly throughout the day. I could be at school and see something that sparks an idea, I can be sitting at the computer and something pops into my head, or I could be having a conversation with someone that gives me an idea. Usually if I'm at school, I'll write the idea onto a piece of paper and maybe outline some sort of script. Then when I get home I start writing the actual script. My vlogs are a lot less scripted though. I usually just outline what I want to talk about, film, then edit it all together.
