Get your nails done! LOL (I'm kidding really) but if you want to save time, then doing the nails with the topcoat and basecoat is a good idea because they last longer, so you'll be doing them less often.
My work is business casual at best. My hair is curly and for work I usually just throw some gel in it, throw it up in a ponytail and that's it. I do wear makeup everyday though. I don't wear face makeup or lipstick. I wear eyeliner, shadow and mascara. I have problem skin and sometime I spot cover up spots, but I don't smear on foundation or powder, its bad for my skin. I hate lipstick but I do wear lipgloss.
My worse habit is not ironing! I hate ironing with a passion! Usually what happens is something wrinkles, it needs to be ironed. I make a pile. 5 years later I donate the pile to goodwill!!! LOL Soooo bad, but I absolutely HATE ironing and Im soooo bad at it that I get frustrated and things always end up looking worse than they did, its such a waste of my time! BF is a good ironer. Sometimes he'll iron something for me plus he really likes the iron I bought. I bought a stainless steel shark iron about 6 years ago and really I think Ive used it twice. I had it more than 3 years before my girlfriend came over one night, used it for a blouse for me for the first time it was ever used! LOL
Picking out clothes the night before does save time in the morning. Early sat morning nail painting lets you go all week w/o doing it again. I straighten my hair (which takes an hour) on sunday evenings and it lasts until saturday morning so I go all week with it, which saves me time.
