I wear liquid eyeliner every day. I feel you though. I was too lazy to wear makeup to school up until this year when my classes started later in the day and I had extra time in the morning. Still, I don’t put that much effort in it. I use a liquid eyeliner pen because it takes a minute or two to apply, and it’s easy to remove at the end of the day.
If you’re too tired in the morning then don’t bother with like full-on makeup. Wearing minimal makeup is all about accenting one thing. Maybe try a tinted lip balm to draw attention to your lips. You can try what I do to accent your eyes. Some girls wear only mascara, but I prefer eyeliner because mascara is more annoying to wash off. It’s really a preference thing. When I had to be at school at 7:30, getting enough sleep was more important to me than wearing makeup.
Also, Neutrogena’s makeup remover towelettes are great. :D
