I can see how it'd be really easy to feel this way. As I learn new techniques and start adding products to my routine, it can start to become an "obligation". I sometimes feel like I have to do everything everyday because I'll look "unfinished" if I don't and, also, I've gotten used to how I look with a full face.
My make-up is for fun. I enjoy it and do it for me because, honestly, I don't think any of my friends or coworkers even notice what I do with it. And it's totally OK to just wear mascara or even nothing if I don't feel like messing with it.
