No matter what you do, or what you're trying to do, always try your best, it can and most likely will pay off in the end. or at least it will make you feel good.
If you fail, at least you know you gave it all you got, and then you'll know it just wasn't meant to be. If you succeed, well then great! Either way, whether you fail or succeed, you'll know where to go from there.
I'm also one of those people where i try to look my best everyday, first impressions are what matter most. Besides, you never know who you'll run into that day! Would you want to meet a celebrity in your hair up and sweatpants? or would you want to look cute?
When you're at work, put on a smile, and give it all you got ! Who knows, maybe you'll be rewarded with a promotion. As humans, we always strive to be better than someone else. Well you can be. Although there will always be someone above you and someone below you, it doesn't hurt to try to keep moving up.
Wishing you all the best,
go climb those stairs and get to the top because i want to see you all succeed!
