Plan ahead for meals, and if possible, internet shop for groceries. Or do a big "stock up" shop now for things that are staples and can make easy meals (tins of all sorts, pasta, rice, couscous, packets/jars of sauces or good seasonings, dried mushrooms, stocks, jars pesto, part baked bread rolls, wraps, long life gnocchi etc for cupboard; frozen veg already chopped (and mixed), packets like a stir fry that's frozen, a couple of good ready meals; etc).
Organise your day:
It may seem odd that I start with the evening but bear with me.
Come in from work, empty out and dump bags, get dinner sorted, deal with post and listen to DD etc.
Eat, then washup. Washup time also includes any prep needed for the next day - peeling/chopping veg, taking things out of freezer to defrost, perhaps making a sauce (I'd normally say things like Spag bol, curries, chilli - but any veggie meals that need slow simmering time). Also make any lunches for next day - for you or DD to bring with you and pop in fridge overnight.
Get any chores needed done then as well, before relaxing.
At bedtime, lay out breakfast things before leaving the kitchen, and otherwise leave it tidy. Leave your work things, handbag, etc, all ready to go. Upstairs, lay out your clothes for the morning while changing and doing ablutions, and then get a good sleep.
In the morning, you can then be in more autoilot mode. Up, washed, dressed, make sure DD is up, get both of you fed, grab lunch, grab coat/bag, head out door.
A good travel mug is great for commuting to fill at home, and having podcasts or an audio book to listen to.
Put bills on standing orders/direct debits where possible, or at least set up for mobile banking.
Having a drawer of general birthday and other occasion cards, spare stamps and envelopes and notelets/writing paper are very handy. I also have a stock of gift bags and various types of wrapping paper/ribbons and tape, so even if I need to grab a gift in a hurry at lunch/order online, I can at least wrap it nicely at home.
Think ahead for clothes where possible. Try and get at least the basic essentials online where fashion and fit are not such an issue (if you are a standard size, things like socks/underwear/nightwear/basic tshirts & jeans etc). So your precious spare time to shop can be used to find a few fun things.
For me, I have a fairly standardised look for work - plain trousers, plain ribbed poloneck jumper or plain long sleeved top or plain short sleeved top (depending on season) and comfortable but respectable shoes (lots of walking), with some dresses thrown in and the odd suit. My jumpers are various colours but a standard M&S pattern that has been going for at least 10 years so I can renew as needed. My tops are LandsEnd, standard shape and fabric, but again various colours. I often manage to get new ones (to replace ones looking a bit shook) with a discount code or in the sales. But it means I can have fun with scarves and jewellery, or jackets/cardigans to go over them, which are what I spend my in-store shopping time on. (Quite often, that might be a few minutes at opening time on my way to the office on quieter mornings, or at lunch or heading to the train in the evening).
And do get good quality clothes that will last and look after them well - they really will save you time and money in the long run!
I have a full makeup kit at home, a full kit in my desk and a full kit in my always-packed travel washkit. I tend to keep the more sparkle stuff at home for going out at weekends, but otherwise, all 3 are virtually identical. Sometimes I have time to do before I leave home, sometimes I only get time at work (or decide I don't need it then someone calls a meeting!), and i do a lot of travel so keep my travel kit full and ready to go (I refill my small bottles when I come home and repack it then as it's sometimes short notice but usually chaotic when going but much calmer when I just get home).
Get a good haircut now, and learn how to manage it quickly and easily. Think about any other grooming and maintenance - find beautician or whoever you might need that you can pop in at lunch or on the commute if you can. And things like doctor, dentist, optician etc too - especially if the ones near home don't do evenings/weekends.
Find good people to help.
Cleaner for home.
Dry cleaner, shoemaker, dressmaker (for repairs) etc to keep the wardrobe looking good.
Repair trades for problems at home - just have their numbers so you can call and organise yourself.
One thing we do to keep laundry under control is to wash as needed during the week (usually organised as part of the "washup after dinner and household chores time but set up on the timer), hang on the clothes horse overnight or throw into the dryer if the washing line outside is not an option (and we don't care about them getting "darked on" so they stay out overnight) - but throw them in a separate clean clothes hamper downstairs once dry. So anyone can rummage through that if they need clean things during the week, but DH or I pick a quiet time at the weekend to pile it on the floor and fold all the clean things at once - usually watching a movie - and out them away then. Or throw ironing back into clean hamper until they are ironed while watching countryfile on Sundays.
Oh, and on food, find some good batch cooking meals if you can, and put a few meals in the freezer for mad nights. Don't give yourself grief for the odd midweek takeaway or dinner that is a part baked baguette cooked alongside an M&S Welsh rarebit cheese thing and a glass of cold wine. Use delis or places like M&S for conveniences in between more wholesome HM meals. Individual plastic takeaawy containers can be great when washed for freezing individual portions of batch cooked dinners - which might be after a whole day doing a few different things, or just an evening where you've had a bit of time to cook and done enough for 2 nights not just 1 so freezing leftovers for another night.
