Which biases would you like to keep?

It probably wouldn’t be an unalloyed good for me to overcome ALL the biases. I overestimate my future emotional reactions to winning or losing, and I’d like to keep that bias because it helps me win and not lose. I remember only good things about the past, and I’d like to keep that bias because it makes me smile. I underestimate my relative competence at things I’m genuinely good at, and I’d like to keep that bias because it encourages me to improve. Which biases would you prefer to keep even though you know you have them?
