He’s also touching on the importance of being willing to swallow your pride or apologize, for the greater good. If you “cross” or wrong someone once you’ve “missed a few turns”, don’t let that bridge be burned because you wouldn’t apologize or own up to being wrong, out of pride (This point is illustrated in the example he gives with trying to warn his friend about the girl he chose not being trustworthy, and his friend “missing a turn” so to speak by not listening to him, likely out of pride/not wanting to hear or believe she was untrustworthy, since he probably loved her. Cole may have been upset with him for not initially listening once the truth was clear, and is advising him to do what’s right now and own up to it, regardless of if pride makes it difficult, for the greater good, their friendship).
