Sebastian Butera Dady is a quiet unassuming young man. He is exactly what you look for in a leader: someone who does not boast about his achievements, but whose achievements boast about him. We may never have even had the pleasure of hearing his story if he had not been assigned by iDebate Rwanda to 'chaperone the trainers' during our short stay.
Still in his early 20s, Sebastian runs his own business, volunteers for iDebate, and has just started an education charity for child refugees. He is also an active member of Junior Chamber International (JCI), a global network for active citizens just like him.
Sitting on a short wall next to the auditorium where the grand final of the Debate Camp Rwanda competition is about to take place, he tells me about his role model, the person who inspired him to be the man he is today: his mother.
"I grew up wanting to help people. It was the way I was raised by my parents. They would always tell me there was a reason I was here. My mum particularly inspired me. Every time my friends came to visit, she would listen to their problems and mentor them. This is why I joined iDebate. We are all volunteers who want to help people."
I take a moment to appreciate the eloquence of Sebastian's answer, reminding myself that like most Rwandans he has only been learning English for a few years and is more naturally accustomed to speaking French.
I ask him where he finds the time to volunteer for two week debate camps (virtually all the iDebate staff juggle voluntary debate training with full time jobs - mostly as teachers).
"I have a small and growing company providing ushers at conferences and events, called Ray Speed Services Agency Ltd, which I hope to turn into an events management company one day."
"My independence is important to me, which I am determined to work for myself. It also frees up my time so I can volunteer for projects I care about, such as iDebate, and another charity I started to collect clothes, school books, shoes, and stationery for young refugees from both Rwanda and the DRC (Democratic Republic of Congo)."
Sebastian doesn't stop there, though. He also visits the children himself as a motivational speaker with the aim of inspiring them to realise their full potential in the same way his mother did for him. He listens to their problems too, moderating group discussions on how to overcome the obstacles to integration in mainstream Rwandan society.
However, public speaking did not always come so naturally to Sebastian and he endured many years of frustration until he met Jean-Michel Habineza, co-founder and international co-ordinator of iDebate.
"I started coming to iDebate after seeing a message from Jean-Michel on facebook announcing a training session. I heard about him from other people and wanted to be trained by him.
It helped me because I was very shy and afraid of public speaking. Also my English wasn't very good because I only spoke French. It was frustrating because I couldn't speak even though I always had something to say."
Now, Sebastian is himself an iDebate trainer and mentor. However, he remains conscious that he still has a long way to go in his own development as an entrepeneur, which is why he joined Junior Chamber International (JCI).
"I am a member of the JCI because they share my vision and desire to help people. I go to lots of their events and conferences in Rwanda, where small business owners like me can find mentors, learn how to write business plans, and build our networks."
I check my phone and more than half an hour has passed even though it feels like less than five minutes. We stand up and I thank him for his time as we head into the auditorium, where 150 more young active citizens are gathered to hear the final debate of an unforgettable camp.
