It really depends what age you are, if you have children or wether you work.
Im retired and getting my house ready to sell re divorce so will have to declutter massively.
My routine is to wake up naturally (I often sleep really badly) so this makes a huge difference to my motivation the next day. I sit and have coffee x2 and read.
Get showered and dressed, make bed and tidy my room. Kitchen to unload dishwasher, generally tidy, load washing machine, clean counters.
3rd cuppa and read (ipad or book). Have lunch. By then it’s usually about 1 or 2pm. Then I settle down to get on with ‘stuff’. Summer it’s often in the garden. In wet weather I will usually do something like sort cupboards, ironing, clean windows etc. i hoover, mop floors, do bathrooms once a week.
At the moment I am spending the afternoons doing some painting and decorating Eg skirting boards and door architraves. When this is done I will start the decluttering.
I usually finish when I’m either bored, tired or have finished the job. Could be anytime from 5pm onwards.
I tend to watch tv from 7pm onwards, I will cook my dinner when I start getting hungry. I go to bed mostly between 10 and 11. I tidy kitchen and load dishwasher before bed.
This may be way too detailed for you, or is is not appropriate. I find reserving a chunk of time in the afternoon works for me. I also do the jobs I feel like doing (within reason).
The thing is, I get way more done in the house with this system than my STBXH who will get suddenly very busy with new projects, which he leaves unfinished. He wastes a lot of time doing nothing, (watching you tube) but endlessly says how busy he is. All those unfinished jobs from 15 years ago now have to be done before we can sell. He is beside himself in feeling hard done by.
