Musar על אבות 4:3

How many hundreds of children are mischievous, following their heart because they see a void before them without a solution. And the truth of the matter is the opposite, only someone who can turn their minds around, only after he reaches perfection will he then be stirred to see that which was taught to us by Chazal, “do not despise regarding any person” (Pirkei Avot 4:3), and the tale of Rebbi Prayda proves that he uncovered this path for achieving perfection.
