Lots Mike! I may be nearing the end of the student grades now but to progress to Dan grades (black belt) is a real lot of work and at least five years away... It's like starting again.
To put it into car terms... When you start you know roughly what a gearbox is. At my level now I understand how a gearbox works and could swap a duff one for a good one... At black belt level you can also rebuild the duff one... The further up the Dan grades you go the more you can do so at the top level you could overhaul a 4HP20...

Probably telling you old hat but always make sure you have a good feel inside the tyre where the hole was, nothing worse than pumping up the tube only for it instantly to go down because the thorn / nail is still in the tyre.
I learned that the hard way when I was a kid James

I've been fixing punctures since I was riding tricycles! One of the very first cycling maintenance skills I was taught when my age was still very much in single figures!
On my daily rider I'm in the habit of carrying a spare tube now and a CO2 inflater (wonderful devices they are!) and with QD wheels and being able to slip the tyres on and off without tools makes it all very easy to fix a puncture now...
On my best bike with tubeless tyres (and my mountain bike) punctures should never be a problem as the tyres are filled with latex sealant and any punctures occurring should instantly seal. I still carry a tube and CO2 inflater with that bike just in case though...
On my best bike, getting the tubeless tyres off the carbon rims is a bit more difficult and needs special carbon-compatible levers to avoid damage to the rim... Also, special (premium priced) brake shoes are needed too...
