I’d suggest getting an old computer to work on for practice. Buy good tools, cheap crap just makes your life miserable.
Buy a pearl catcher, perfect for holding screws in fiddly places, 4 small claws grip the head of a screw and allows you to locate it into the screwhole. You can also get screwdrivers with same claws at the end, so you can drive it home too. Magnetic holders isn’t a great idea around electronics. A grounding strap is a worthwhile purchase to remove static charge from your body.
I have a very good spacial awareness and can “seee” what I’m working on, as in I can visualise the whole thing. I’ve rebuilt car brake systems too, fixed exhausts, replaced suspension parts, and do lots of DIY/plumbing etc.
Practice makes perfect. As a child I used to dismantle old tape players, TVs, lawnmowers, cars, etc.
Wiring the house was easy, once you got the ring mains sorted out. So the electric leaves the distribution board, goes to first socket/switch, to next, next, next, then back to the distribution board. Lights go to the ceiling rose usually, then it is twin brown and earth to the switch. I’ve toyed with doing Youtube videos if there would be demand, I am moving and doing a lifeskills & counselling course along with a supported employment certificate, as I currently help disabled people find employment. I’ve done a motivational speaking course, so will be building that up.
As regards appliances, they usually have generic issues, tumbles tend to blow the thermostats. 2 thermostats cost me £6 to buy off Ebay, which saved me shelling out on a new condensing dryer. They are located near the heating element; typically a box shape sticking out the back of your dryer. They are round, about 20mm dia and have 2 mounting lugs. Wires plug into them. If they overheat, they blow. Overheating due to lint filter not cleaned out and drum temp gets too high

Hi,I wrote a longer reply to another comment. I said about using a pearl catcher. It is about the size of a retractable pen and has 4 small claws and is handy for holding small screws. You can go fancy and buy a screwdriver with same on end of it, so it secures the screw on the driver tip and you can then drive it home once located. 😊

Yes, the current colour detectors are grim. I use Tap Tap See, or BME, where you get a person to ID them, or just facetime someone. A detector which you can put the cable into would be perfect, as when I fitted the Euro Socket in my classic car, to make installing new stereos easier was a headache, and I needed sighted assistance to get the colours for locations, then use my meter to pick up in the car for a switched live, permanent 12v supply, light spur for cluster lighting then the speakers.I’m waiting to get a student keen to make a unit, bound to be laser analysis available at a sensible rate for colour detecting. 😊

Hi, I should have, if you can give me until tomorrow evening, as I am at my Brother’s over the Easter holidays and I’m not at home. Yes, it is a good multimeter, but I had to order it from the US with a group of VI people, as it was a minimum order for shipping to UK. I think I have the instructions, if you drop me a DM I can share my Telegram ID and fire it across to you.
