Of course there are. I'm far from perfect and fall dramatically short when compared to competent professionals.

However, you're missing the point. I'm talking about people I actually deal with in my life. People, through virtue of the position they hold, that I fully expected to be a cut above the rest of us.

These people have jobs that I personally (and I suspect many others) assumed would demand a level of expertise and dedication that puts them beyond the reach of most ordinary people.

Turns out I was wrong. These positions are teaming with unremarkable folk who seem to have decided that that's what they're going to do and have got there.

Perhaps the real issue is a lack of self-belief on my part, but I don't think so. I'm aware of my limitations, so therefore I'd never seek to become, say, a doctor.

Having dealt with countless inept professionals I can only conclude that they were not deterred by their own shortcomings the way many of us are.
