It's just one part of the entropy, like you can use a personal photo to create entropy. You still add more randomness.

Indeed. It's so very "human" to try to "outsmart" the work of decades of cryptography and computer science.
It's hard to believe that there's an "optimum" amount of randomness; that you can't just make more and more.
