Yes, pride is the biggest obstacle to growth. It prevents you from making our needs known, because it means making an admission that you
lack something (like knowledge or understanding, in this case). It means being
honest about what you are (humility), revealing your deficits. And we all have deficits. We all have lack. Love is about seeking and receiving what you lack (eros), and giving to those who lack what they seek (agape).
So what does this tell us, this tendency toward pride? I means many of us spend a horrifying amount of time posing, pretending, feigning worth we don't actually have, in order to appear to be something we are not, because we think this will get us things we couldn't by being honest. In order words, we're liars, fraud, and cheats. We lie to get things we know, or least believe, we do not deserve, through false advertising. And we fear being belittled and ridiculed and put down, or losing or losing something. We shirk responsibility this way. We confuse purity with a kind of "cleanliness". We want to appear clean, but become impure and corrupt in doing so.
The choice between pride and humility is, I think, the basic decision in life one must make, and keep making, and it can be difficult as the world does not make it easy to prefer what is good. It seems to want to reward you for pretense, and punish you for honesty and the truth. That's why you also need courage, the courage to surrender to the consequences, of doing the right thing and being humble, and embrace them. You cannot control anything but your actions within your limits. You need to be able to accept just but painful outcomes gladly, and suffer the injustices. The inability to suffer, to suffer injustice, is the gateway to pride, and pride comes before the fall, before death and stagnation. You get further in life by suffering and moving forward, suffering and moving forward, suffering and moving forward.[0] There is no life in you otherwise. There is no love in you otherwise.
[0] This is also why the Via Crucis is so powerful. Life is not a party or a pleasure garden. It's a struggle that ends in death. The only choice is one between miserable comfort and wasteful decay on the one hand, and struggle, suffering, and total exhaustion on the other. The Via Crucis, a road full of suffering that passes through death, at least ends in final liberation. But that is the price, the narrow gate. Most choose the wide gate of miserable self-preservation, something they will loose in the end anyway.
