Lessons learned

For a bit of background, I'm the youngest person in my department and have less experience and skills than anyone in my team. I've only been in the industry for a year and have been working for the company for less than that. Today, I hosted a meeting that I was woefully unprepared for and I misunderstood the meeting topic. Individuals in the meeting included analysts, managers, and senior managers. It was 30 minutes but felt like an eternity because I was fumbling around trying to find materials and didn't have the data prepared ahead of time. My manager ended the meeting early before I could continue making a fool of myself and apologized to everyone on the call. After my performance, he told me to stay on and let him know when everyone left. I expected to get chewed out worse than a starving person eating a rack of ribs. He told me that what I did during the meeting can't happen again but let me know that he is not angry or upset. He stressed that if the same thing were to happen in front of a more senior audience, there would be drastic repercussions. He shared that everyone has been in my place at one point and how he's made far worse mistakes in his career. Following this, we spent the next three hours discussing how I can improve and what to do for next time. He then set up a meeting at the end of day with the same individuals to represent our data in an organized fashion. The meeting went extraordinarily well and everyone on the call was pleased with the outcome. He's allotted more time tomorrow to continue helping me. After a rollercoaster of emotions, I couldn't ask for a better manager and I've taken this as a learning opportunity to reach out for help when needed.

TL:DR

Young person (me) unprepared to host meeting botches it and manager wants to talk after. Manager spends hours explaining how I can improve and sets up another meeting with the same people to represent data. The meeting goes much better than the first and everyone is pleased.

EDIT:

I can't thank y'all enough for all the support, advice, feedback, criticism, and praise I've received from all of you. I know it's still early in my career and these things happen but what's important is that I grow from it. I 100% echo the support and praise for my manager, no, leader as so many of you have stated and I strongly agree. I am fortunate to work where I am, with some of the best people I've ever had the pleasure to meet. I am truly blessed.

Also, I saw a good bit of people sharing their own stories about managers and their ability to build up or tear down employees. I believe in y'all and if you ever want to talk about your experience or anything at all, I'm just a message away!
