My self-discipline is at rock bottom, and it does worry me.
BC (before computers) I worked, took work home for the evening and still managed to keep on top of housework, do the garden, cook lovely meals and feel in charge of things. I sewed too and brought up three children and although life was hectic, I coped and felt a sense of urgency and the need to keep some semblance of organisation.
What happened to me???
Now I only work two half days a week and in virtually all my spare time (when I am not with fiancé and getting out and about) I do sod-all around the house. I keep the guest loo spotless and the living room in a reasonably tidy condition (but don't inspect the carpet too closely because the vacuum cleaner doesn't get an outing often these days) because if visitors call I won't be too ashamed of my sloth and slovenly ways. Other doors in the house stay firmly closed! 
It's awful. I don't watch much day-time TV because I think so much of it is rubbish, but who invented flippin' catch-up TV? I can watch decent TV progs during the day now. My laptop is also much-used. I have thought of secretly stashing it in son's car so he takes it to work with him each day and then I'll have time to do the jobs that are piling up!
This laziness/self-indulgence brings with it such guilt. Having too many days in which I achieve very little doesn't bring satisfaction at bedtime. I know this is my time and I can say "I am worth it!" after being busy for much of my life, but I am afraid that doesn't wash or make me feel good about the time I waste. I actually set an alarm on my phone now for late afternoon to remind me to get up and start preparing the evening meal.
I need someone to confiscate my TV, laptop and books. I might then move myself a bit more and spend my time more productively.
