I sit down in front of my computer or the TV, and I automatically want to munch! I realize it's because I'm watching something and being inactive, and I want to keep my hands busy, so I drag my nail box out, and start soaking, filing, shaping, and polishing. If you take your time, this could last an hour, and you'll have the best looking hands EVER. It's all about pampering, and spending time with yourself mindfully, and not stuffing your face mindlessly.
Even if you're not into wearing makeup or nail polish, try using a clear polish, your hands will still appreciate the attention!
