history: My coworkers and I were each tasked with individual projects and whoever performed the best would get a promotion. My coworker killed it and got the promotion. I really wish I was as good as her. My boss tasked my coworkers and I each with an individual project and whoever did the best would get a promotion. My coworker blew us all out of the water with her project. I only wish I had her skill... Wow. I'd just use that as motivated to get better. I'm sure you can get to her level or exceed it with some deligence.
current: I don't know, I felt like I tried pretty hard and poured my heart into my project and still didn't come close. It kind of feels unfair. Maybe she's juts naturally better than I am.
next: We can't compare ourselves to others. It'll just make you miserable. There will always be someone who is better in something. You could be better at something that someone else isn't.
