> You wouldn't believe how many times I've had to try to convince younger engineers that we don't need to over optimize and can't initially create the perfect solution because 9 times out of 10, the feature will change significantly, or get abandoned completely. Or it performs well enough that it's not a bottleneck in profiling (and deliberate performance optimizations are unnecessary).
