I was lucky during my first two months of pupillage.  I got to observe two substantial High Court clinical negligence trials which my supervisor was acting in.  That was quite an introduction, and doesn’t happen often for a pupil.  I saw some of the finest advocates at the Bar at the top of their game, which left me with a clear idea of what to aim for in my own career.

The hardest part of my professional life is when I have to explain to bereaved parents why compensation for the negligently caused death of their child is so modest.

“Team work is very important.”

I am happiest at work when everything “clicks”.  This is the moment when everyone working on a case is in harmony with a shared goal, and we all know exactly what we have to do.  This requires hard work and preparation, but also the sharing of ideas and good communication.  Team work is very important.

The best piece of advice I have been given is to concentrate on being good at my job, and to let the rest take care of itself.  I find it helpful to focus on that in moments of self-doubt.

I have learned how important empathy is. We need to be able to understand our client’s perspective, but also how the case looks from the other side of the fence. If you can’t see the case through the prism of your opponent’s eyes, it’s much harder to present your case effectively.
