I enjoy socialising, travelling, and am passionate about sport. I also enjoy running; and while taking part in a Remembrance Run I saw a sign that read: “Forget about all the reasons why it won’t work and believe in the one reason that it will” which is a message which has remained with me personally and professionally since and inspires me to bring a sense of continued positivity to my role.
