In the post you're correct, where you're not talking about pride, but about loving what god has entrusted to you.

There is pride as a form of satisfaction for something done well. That is not sinful; it is the feeling behind a self-reinforcing mechanism to better oneself.

Then there is pride as a form of vanity, like jealousy but with the participants reversed. That is sinful; it is the feeling behind a mechanism to cause jealousy in others, because they weren't gifted (by god) with the same circumstances that you (undeservedly) were.

IOW being boastful-proud of something you did nothing to achieve, is sinful. Being satisfied-proud with the result of one's actions, is without sin.
