Don't have much to say about how to do things, but I'd say try to reduce the number of things to do, so the little you still have to do won't be a big deal.

For example, I only communicate with companies/suppliers via email/phone (and change suppliers if they can't accommodate that). This means any physical mail that arrives must be spam, and goes in the trash without even being opened - anything I care about would instead come through phone or email. This means I haven't needed to fiddle with papers for ages, while my flatmate still wastes a good 10 minutes almost every day reading incoming mail (and then putting it into a huge pile she'll eventually have to sort out - akin to technical debt).

Bills are paid out automatically (via "Direct Debit") so I don't have to worry about that either.

Shopping is taken care by Amazon subscriptions, which means new stuff arrives soon before the old boxes run out. Haven't been grocery shopping in ages.

Food is handled by Deliveroo/Uber Eats, so no cooking necessary. I use throwaway forks & plates so no dish washing necessary either.

Cleaning/housekeeping is handled by a company that does it every week in the flat while I'm away, so no worries about that either.

Not all of this is possible for everyone (things might be different depending on your location, whether you have a family, your financial situation) but personally it works great for now and I have plenty of time when I get home. Basically for anything that you're doing, try to see if there's a way to not do it at all or to outsource it to someone else (who might be an expert at it and thus do it more efficiently than you can).
