I'm sometimes thinking about an implant, but then I realize a ring or bracelet would work better.

A current concept I've been fiddling with is a personal assistant that's always on me.

Yes, a phone, but strapped to my back. Why? Because I can't leave it somewhere or change the volume or ignore it.

It's meant to nag me until I finish the task (verification/confirmation is difficult though).

That's a smartwatch. Obviously you need an incentive to wear it continually; that could be exercise (step counting), health tracking (heart rate plus (as of a few months ago) pulse oximetry), etc.

Also you can get contactless payment, and it can even tell the time.

After a few months you get used to wearing a watch continually again.

That's an option, but I hate watches. Always have for some reason, even when it was the only portable accessory I had it in my pocket.
