I'm always thinking of stuff; I just don't sit down and write it. I come up with material more as I go along; if something funny happens, I'll make a note of it on my phone.
Sentiment: NEGATIVE
Write down everything you can think of, no matter how stupid it seems. I always write down my thoughts throughout the day. Sometimes good things come out of it, and I'll find an idea to develop into a song, so my best advice is to try and draw inspiration from everyday things.
