Last month, I had to write performance appraisals for my team. This used to take me 4 hours per person. This year? I used ChatGPT and knocked it out in 60 minutes per appraisal—and they were better.I gave ChatGPT context on each person's goals, specific examples, and areas for growth. It structured everything, highlighted patterns I'd missed, and helped me articulate feedback clearly. I still edited for tone, but the heavy lifting was done. Three hours saved per person.But I've also wasted hours this year on tools that looked shiny and delivered nothing. Subscriptions I forgot about. Workflows that flopped.So this week, let's pause and honestly assess: What AI tools and workflows actually deserve our gratitude? And which ones should we leave behind in 2025?
