In five years’ time I will be a doctor with a number of published studies that have advanced the scientific community in small or large ways. I could be anywhere in the world, and I will continue to perform as much meaningful research as possible. While studying for my PhD, I have learned that research is not as intimidating as it sounds and that making mistakes and learning from them is all part of the process.
To future PhD students, I would say you are all capable of doing a PhD, performing meaningful work, and contributing to society and, at the end of it, people will address you as Doctor!
