Let me be dispensable, let me be the one who can be easily replaced, and value me for the skill and commitment to my profession.
I will create robust, maintainable code that is documented well and tests that are easily used. I will be open about the flaws in the software I produce where I know of them, and make myself invaluable because of the quality of my work and not because I make it inaccessible to others, that is where true value lies.
