I dropped my hours around 3 years ago to 28 hours a week (4 x 7hr days) due to caring responsibilities. Wage dropped to around 25k a year before tax. Don't regret it at all. I have no desire to go back to full time now, even if I didn't have caring responsibility.
My outgoings are fairly low though. Mortgage only has just under 16 years left, which means I should be free from that by the time I'm 54 (hopefully even sooner). Plan is then to sell and downsize as I probably wont need the size of house I'm currently in as I have no children and don't really plan to have any.
I'm also not one for spending if I really don't need to. I have no interest in big posh expensive cars (I currently don't even own a car), watches, fancy clothes etc. I'm happy as long as I have something to play my games on, watch TV/listen to music. My other hobby I've recently took up is also cheap too.
