How do you handle feedback without losing confidence?

If feedback is a trigger, try preparing mentally ahead of the feedback session. Take 15 minutes to reset & get in a good headspace. Think about the person giving you feedback & the purpose ahead of time. Listen, take notes, and most importantly remember to say "Thank you for the feedback." especially when you don't agree with the feedback or it's triggering feedback or you don't know what to say (and not offend the person or lose your job!)

Better understanding the triggers and even writing them down with the emotional response that follows can help this process. Reminding yourself that even the best still benefit from feedback can also be helpful

This point is especially valuable and shows your openness to accept feedback which creates a virtuous circle. On the other hand, it may also open the door to a discussion where if you disagree with the feedback, you can share why which may also open up a productive conversation. The key here is not getting defensive and seeking ways to make the feedback useful

Asking for examples definitely helps. When there is no example, try asking for how they suggest you address the feedback. Doing so helps reduce ambiguity. Ideally, feedback is clear when given.

If you're not getting feedback from the right people, it's value is greatly diminished if not even counter productive so pay close attention to that and politely move on but make sure you're honest with yourself about this as it may be easy to say "that feedback is not factual or coming from a qualified person" and then you continue your quest missing an opportunity

Consider how the implementing changes based on the feedback will help or hinder as well as if these changes will help you meet your goals.

Share an update with concrete examples to the person who shared the feedback, this helps you and adds value to the relationship

Consider the impact of generosity here as you likely can also help someone by delivering specific feedback in a positive way. This reverse scenario will also add perspective

Make sure you fully understand the feedback by asking for clarification if needed. Seek specific examples and details to gain a clear understanding of what areas need improvement. Never forget to celebrate achievement on the way 1

Always, always, always celebrate the wins!!! It boosts your moral & mood as well as others. Even small wins matter so be sure to include the good things & the wins.

Receiving feedback is hard. We're humans with emotions & triggers. The important thing is to know your triggers, reference the approaches in the above article, and make a plan for how you handle feedback then reflect on how you did - what went well & what you can improve on next time you get feedback. Self-improvement is an iterative process.
