Real talk: how do people go for more than a day without chipping their nailpolish?
True true.
I keep mine medium-length because I like being able to use them to scratch/open things, but also not so long that they'll break easily.
That's too short for me. That would bug me personally. :P but you do you!
That's totally fair. Mine are about 3 mm right now and that's uncomfortable to me. 1.5 mm is ideal.
