Things I now know not to do next time

[presta]

Never carry your cable lock in the opened position.
I know someone who snapped his lock shut at his destination before realising he had left the key at home.

I always lock the car no matter how long I'm leaving it for. I once pulled into a layby busting for a pee, grabbed the keys, pushed the plunger down on the door lock, and then held the handle so that the door wold lock as I shut it.
Then I looked in my hand and saw that I had a bunch of keys minus the ignition key, which had come off the ring and was still in the ignition switch. So there I was, stood in the middle of nowhere, shirt sleeves, in the middle of winter..............

If you have clipless pedals and take the bike on the car to the start if a ride, take your matching clipless shoes as well.

Upgrade to Windows 10 on a perfectly good laptop.

Never lean the bike against a suitably pricey thing, like your car. It will fall over and put a hole in the tail light.

Never leave gunk filled tubes on a bike for 3 years without removing and checking them.
It's damned inconvenient when the valve rips off the tube spraying green crap like a katherine wheel and the lock ring is jammed tight.

From yesterday - having taken the cassette off etc to replace a broken spoke, remember to replace the plastic thingy that goes between the cassette and the wheel before putting everything back together and finding the extra bit on the table.

you don’t need it, if you mean a pie plate rather than a spacer for a 9 speed cassette on a 10 speed hub...

Make sure you have properly retightened your stembolts before you go for ride inthe hills and have an exceedingly alarming wobble as your loosens as you doing 30 mph downhill.
