As a computer engineer I usually copy reference schematics and board layouts from datasheets the vendors offers. 95% of my hardware problems can be solved with it.

Learning KiCad took me a few evenings with YT videos (greetings to Phil!).

Soldering needs much more exercise. Soldering QFN with a stencil, paste and oven (or only pre-heater) can only be learned by failing many times.

Having a huge stock of good components (sorted nicely with PartsDB!) lowers the barrier for starting projects dramatically.

But as always: the better your gear gets - the more fun it becomes.
