Drink alcohol. For me it usually ends up in two scenarios.
1. One or two glasses of wine and you get really creative (good). Then you have a glass or two more. The timing gets screwed up, you get tired and can’t come up with anything good.
2. A bottle of wine is in your body. You are really creative and everything you do sounds awesome… a hit song is on its way.
You wake up the next day and listen to the result… Not so good.
