It's easier but not impossible. I'm a lone parent of a 5 year old. Not blowing my own trumpet but close friends often say I have a lovely home and am so organised.
I now live in social housing earn less than £20k a year, but my house is like a show home. White walls, grey carpets throughout, no clutter and pops of colour to brighten each room. I keep it clean and simple and definitely low budget, 5ltrs of white trade paint is far cheaper than vespal colour range.
Storage is key along with having minimal belongings. I clean each evening from 7:30pm it's not much there are only two of us, do the packed lunches for me and my son for the next day, and relax with a cup of tea at about 8:30 and watch TV.
I've always been a naturally organised person though, I like routine and don't get bored with it. The house is awake at 6:30am, we have breakfast, wash, brush teeth and dress. He watches TV whilst I clean the breakfast dishes then it's school run, me work 9-5, pick up, tea/play/TV and bedtime at 7:30 for him.
Weekends are time for "family" so parks, beaches, puddles, indoor play areas things like that, cheap and cheerful sometimes the cinema if the budget will stretch. Oh and the weekly shop in Lidl/Aldi on a Sunday afternoon.
I will often pack 2/3 weeks prior to a holiday too, as the clothes that are needed are washed, I'll iron fold and put them in the case to avoid them ending up dirty again just before we need to go.
I'm just "one of those people" I'm a slave to habit and routine, I don't mind it though I find life easier that way. My house is always clean and tidy because there's one adult and one child, I'm a tidy person who cleans up after a pretty tidy five year old who also has learnt to "tidy up".
Some people are like me, some people are not. None are better than the other. Everyone lives their life as they see fit. Some people would say I have a boring clinical life, and yeah I probably do, but I'm happy. So I don't care.
