> the confidence you had when you were 33, and improved humility may also prevent the 'genius' perception, but you're probably already more effective an engineer now than 9 years ago.

I can’t speak empirically to how people’s self awareness changes over time, but this quote rings true for me. I have more humility and a different kind of confidence.

In particular, I am less confident about a lot of things, but even more aware when other people are overconfident. In other words, I know I don’t grasp the complete reality, but I’m damn sure you don’t either. :)
