When you buy components, buy a bag of them. Good for when you let the smoke out of one, and you can have several projects on the go at a time.

Problem with doing that is sooner or later you are going to end up with piles of stuff like esp12f's and such. I have more packaging tubes of ATtiny85's than I will ever use.
When I started there was lots of smoke 😀 it's true that you can easily accumulate random stuff, but I still think it's better to have spares of the things I use than risking running out and waiting for a delivery. Maybe I'm just disorganised.
These days I mostly apply it to passives. Especially small ones. 0201 are a pain to work with, liable to blow away if you look at them wrong. 0402s are better, but still easy to lose. But if I'm trying to keep size & weight down I tend to need the tiny parts, so it's easier to design to use common values as much as possible and spend $30-40 for a reel of 10,000 of them. I doubt I'll ever run out of 10kΩ resistors!
LTspice is a free
I like to learn by reading regular old books. There should be plenty availible. Some textbooks, beginners books for hobbyists, some that go along with some experiment box... Starting with what is Ohm's law to how does an amplifier work, flip-flops / whatever. I borrowed and/or bought some books about Arduino, because that's something I like more than analog circuits. I have one that is focused more on the programming part, but there are books with like 80 Arduino projects. You could try Fritzing or the official website for material and project ideas. But my current life-hack is visiting the library or buying a book that teaches things in a structured way. Unfortunately I can't give specific recommendations. My books are old and not in English.
And another bit of advice, don't do it like me and start like 40 complicated projects and have them all unfinished in some drawer. There aren't really bad consequences with that approach, but I suppose it's more healthy to at least stay a bit focused. And don't get disappointed by starting some projects that are way above your head. You'll get there but it takes some time and effort.
Thanks. Im definitely going to not start a lot of projects. I don't have the time to spread myself thin.
If you’ve got 25 minutes, I made this a while back https://youtu.be/Yzfk0t0HfZc?si=YQRNtg5hHbp-CFcO
Thanks. Some good information there. I dont like throwing out components though...
