I am overcome with the desire to gloat. I have, in my humble opinion, the best job in the world. Now this might be the exhaustion talking but this week has had a great mix of new experiences, further development in existing skills and a real sense of progress. The reason I'm exhausted is that my schedule this week has been chaotic. I've worked on average only 11 hours or so for each of the first three days this week but those hours have included evenings, mornings and a fair bit of back of the clock "flying".
