The Anecdote blog tells of two engineers: an engineers who is 20 years in the business rates himself as "good" while a guy who is only two years in the business rates himself as a professional.
Makes you think, isn't it?
I'd been working on some document for several months, had to put it aside, and returned to it this week. This document - although far for being ready for delivery - is my pride. I love every word in it, and every GIF I patiently crafted from XLS, via Visio (no Photoshop for me, thanks :)
However, there's a lot that needs to be changed in this document. GIF to be improved, text to sharp and clarify, etc.
Why is that?
Because it's the nature of things: every living thing could be improved. Human creation - including documentation (not to mention the technology I'm documenting) - ought to be improved as well. Whatever I'm doing, I can do better.
This is why, if asked, I consider myself an expert. Not because "I don't know what I don't know", but because "I know what I know", I know how I got to know this, and know how to get new knlowledge in the future.
