Things that I've learnt:
1. Doing your nails while typing up study notes really works. Paint a coat of polish, type a page, paint a coat of polish (you get the pattern..)
2. If you paint polish outside of the lines, don't worry! Let your nails dry and then wash your hands in warm water. As your scrubbing away, run your fingernail around your cuticle to remove the excess.
3. If your really in a rush, spray some Pam or lightly brush some olive oil over your nails. This will remove the stickiness and prevent you nails from getting scuffed.
