Respect people with less talent than you. Most of them are working harder for less.

Talent is something you were handed rather than something you earned, and it quietly shortens the distance between effort and result. Someone without it is putting in the same hours or more for a smaller return. Looking down on that means looking down on a person for having a steeper hill. It also costs you, because they know more about persistence than you do.

Find the hardest worker on your team who is not the best, and ask how they practise. Then say what you noticed, directly, where other people can hear it.
