How do you get rid of the toxic belief, that if you think well of yourself.. you are arrogant?

I'm not sure I've got it down right but in one of Pauls letters in The Bible he says consider others better than yourself. So when I think about how I make music and anything else I can be up my own backside about, I always remember there are people who are a whole lot better at doing what I do. Like I said, not sure that's what Paul meant but that's my mentality now. So I have some self belief but I'm never the best at anything.
