From Augustine (cited by Calvin and D. A. Carson, and probably a whole bunch of other folk):
Professional orators say that the first precept for the school of eloquence is DELIVERY. The second precept of eloquence is DELIVERY. The third precept of eloquence is DELIVERY. If someone asks for the first, second, and third precept of the Christian Religion, my first, second, and third answer would be: HUMILITY.
If Augustine’s right, how do I get more humility?
Go At A Walking Pace 
Live in the gospel.
Yours humbly
i’m not sure that it’s something you can necessarily ‘achieve’, especially by any of your own strength or doing…
so pray for it, and then rejoice when God does humble you
yours not as humbly as I ought…
I find that occasionally listening to my sermons online does the trick for me!
