Whoever loves discipline loves knowledge, but he who hates reproof is stupid.
It’s clearly from the verse that knowledge comes from discipline, so if we seek knowledge we need to seek discipline first. Self discipline on accepting our fault and set aside our ego when someone correct us.
As a video game player, one thing that I learned from a professional player when said that pride makes a player weak. I acknowledge that so every time I got mistake and someone reproof it even on good way or saying not a good words on me, still accept it as a learning from my mistake.
