If your code doesn't do what you want it to do, you have no business optimizing it.

Ah, you haven't been out of junior class yet.

If I lose more sales because of performance issues than I lose because of bugs, or missing (edge) cases, performance *is* more important than making it do what I want. Or, if the boost in sales of cutting corners is more than the lost in sales because of the corners being cut, I have all the business case I need to optimize it.

To give an example, if I use software that calculates an "optimal" route for me to deliver packages to 40 customers, I rather have a slightly optimal route that's ready by the time I start driving, then that I've to wait another few years just to find out I could save a few seconds from my trip.

Seasoned programmers know when a solution is "good enough" and performance becomes as important (or even more important) as being "perfect".
