This meditation tends to valid my philosophy of "Never profess to be an expert on anything", because chances are I'm probably not.
It also provides an interesting perspective on what I have observed about myself since I started working as a programmer (previously I was an engineer) a few months ago, namely that my programming methods and skills have been lacking in many areas, but are improving. Now I wonder how many other bad practices I have that I am blissfully unaware of.
I suppose as long as I continue to look back at my previously written code in disgust/dismay etc, then I at least have some chance of continuing to improve. Of course, peer reviews are also a good idea, although I dont know if my fragile ego will cope. :)
