It’s a strange thing but there’s a direct line from creative desire to buying then not doing.
This is why I have so much electronics junk it’s all projects that I “completed” when I hit the buy button on Aliexpress.
Also I need to sell an oscilloscope and a bench power supply :)
Point is: Having the drawers of 'I'll save this just in case!' in all hobbies does in fact come in handy. I find this especially true when some sort of project requires 'yet another adapter' to convert thing a to thing b. Project either goes through or it doesn't, but later on when trying to attack something else, having that little drawer full of weird but useful cables and adapters within living room walking distance sure feels rewarding.
