Renowned talent agent and manager, Professor Jonathan Shalit OBE, recently shared insights on how he has maintained his company’s success in the constantly evolving entertainment industry. While there are likely numerous factors contributing to his achievements, he emphasized his aversion to a certain negative mindset. He mentioned that during meetings, if someone were to express sentiments such as “The business isn’t what it used to be” or “Things aren’t like they were,” he would promptly conclude the discussion.

This perspective resonated with me. It highlights a valuable approach to remaining relevant and optimistic by refraining from dwelling on a past that may not have been as favorable as we remember. What purpose does such nostalgia serve? Yet, it seems many of us are preoccupied with thoughts of a better past—whether it be about life, the world, or personal achievements. It’s no surprise that much of our political dialogue reflects this sentiment.

Conversing with Jonathan made me realize that my outlook is quite the opposite of his. This realization has illuminated one of my shortcomings, particularly in my golf game. I struggle to move past my poor shots, not only those from a single game but all the bad shots I’ve ever taken. As I prepare for my next swing, memories of past mistakes flash through my mind, hindering my ability to envision a successful outcome. I can almost hear the sound of the ball hitting trees or splashing into water before I even strike it.

I’ve decided that I’ve had enough of this cycle. I’m going to adopt some of the positive mindset that Professor Shalit embodies and change my approach.

However, before making this shift, I picked up my daughter from Heathrow’s Terminal Three this week. The experience was far from pleasant. The terminal was overcrowded, unkempt, and chaotic. I paid ten pounds for a coffee and a bottle of water, and parking for less than half an hour cost twelve pounds, most of which was spent searching for a functioning ticket machine. It was a dreadful experience, especially when I think back to how magnificent the terminal was after its refurbishment in the early 1990s. Those were truly great times.
