Something I've struggled with for a number of years, both professionally and personally, is communicating with people who aren't developers and know little to nothing about the nature of my job outside of its necessity. They often don't know that writing software is a juggling act of considerations and compromises. Sometimes you have to sacrifice flexibility for performance, sometimes you give up performance for flexibility. Logistics rarely allow for a silver bullet to any given situation and you frequently have to decide which is more important.
