I never have time to get my nails done anymore. Besides, the nail polish never lasts long because of my job (food service). Literally the next day my manicure is ruined because of work so I don't bother.
I've had acrylics done twice for a wedding and for my senior prom, and I can honestly say that I will never do it again. It absolutely ruins my nails for a long time and I can't stand it. Luckily I have very strong and nice nails naturally, which is why I don't want to screw them up with acrylics.
Now, I just keep my hand nails fairly short (maybe 2 mm? I suck at measurements). Not too short and not too long, because if they get too long they end up breaking off.
For my feet, I cut the nails short with almost no white part showing. I don't like the whole dirt-under-toenails look.
