I don't think pride and perseverance destroys an individual. They are actually really great tools if you know how and when to use them. With me, the problem was that the pride that I felt, wasn't earned. It was an illusion that I subconsciously adapted to.
About perseverance though, I think it's one of the most important factors when you are trying to achieve something. Perseverance works with empathy in relationships, not against it. If you keep walking away from someone because they are too much to deal with, you'll never be able to make a connection.
But if you have empathy, you'll persevere and try to talk with them even if they are being unreasonable and a little difficult at the moment.
