Just no way. If you want to be a perpetual loser you think like that.
I think of it like building a computer, AR or a bike, you can't just choose from the best components available, you have to pick components that are going to be compatible and work well together to accomplish the complete system that will produce the results you're looking for.
And say you already have said system designed with the best components you were able to afford at the time, and you're now you're back at the candy store looking to tweak said system. Well, you can't be in perpetual design mode ... the rubber meets the road when you build and test your system in the real world, which obviously is hard to improve if you're working with a perpetual failure instead of methodically tweaking your own design.
Now components may fail (injuries), and when that happens you have to fall back on parts that are readily available on hand, at which point it really matters how much deviation you have from your design and what's readily efficiently available
