The way to overcome that is to start off with broken gear and to repair it. You'll be forced bit by bit to understand how the circuits work. It helps if there is a schematic and if there isn't then you'll have to trace the circuit yourself which will help even more in building up a mental model. Of course this all presumes that there is a circuit worth examining to begin with, more often than not these days you'd be looking at a bunch of custom made chips and a few external components too large to fit into the chip which itself contains a microprocessor and a bunch of software to do the heavy lifting.
But pick up an 80's tape recorder or amplifier that's busted and you're going to have fun learning. Start on the simplest stuff you can find and work your way up from there.
This bench really looks focused on hobby prototyping, nicely done with that in mind, and with the proper assortment of components in multiples so you can go from idea to funtional circuit directly without encountering the show-stoppers (or delayers) that can be so common otherwise.
A repair bench can be made to avoid a somewhat different set of show-stoppers, there will not only be a number of different things more useful at your fingertips, but a deep store of off-bench material and tools still accessible allowing much more powerful operation. Also taking up much more auxiliary space than any one optimized bench.
Either way you never avoid all the unforseen show-stoppers, so you need a clear location to shelve & preserve an incomplete prototype or repair/restoration project, for instance while waiting for parts, in order to fully clear the bench for other work which can then be quickly accomplished from start-to-finish.
And then there's the "production" bench for hobbyists where prototyping and repair is not so much of a consideration.
