Is There Anything You've Learned That's Going Against What You Used to Believe?

Is there anything recently that you've learned or picked up that's gone against what you used to believe or used to practise? Maybe in a coaching context. My philosophy is that you should never really change that whole scale based on one learning episode. i think the biggest sort of thingtat stands out to me in the modern world, modern world coaching,. is ar the differece betwen coaching and instructing. I would like to consider myself more as a coach than as an instructor - although i will obviously at times fall prey to instructing people rather than coaching.
