Kendrick Lamar, considered one of the most talented rappers of his generation, makes a note when he feels inspiration so that he can re-access the emotion later.
I have to make notes because a lot of my inspiration comes from meeting people or going outside the country, or going around the corner of my old neighborhood and talking to a five-year-old little boy.
And I have to remember these things. I have to write them down and then five or three months later, I have to find that same emotion that I felt when I was inspired by it, so I have to dig deep to see what triggered the idea. It comes back because I have key little words that make me realize the exact emotion which drew the inspiration.Kendrick Lamar
