Once again the PhD is so like a developing baby. When my boys were just about to crawl they were so frustrated. Objects were just within reach yet the effort seemed too much and a grizzle was so much easier. As the parent I noticed time and time again just before they reached a milestone they were horrid, then when the milestone was reached peace and harmony was restored. Such milestones included crawling, teething, talking and walking. Well my PhD is so similar. Today I had a win with an equation featuring the letter “e”. Binary logistic regression and probability for those statistically and mathematically inclined. My maths is not really at this level so it’s been a huge milestone to reach with much grumbling and cursing by me. Today I felt alive with happiness at reaching this huge milestone. I ran along the beach at lunch unable to wipe away my smile. My poor family might finally have a dancing happy Mum again. Who would think the letter “e” could bring such delight.
