— Not professionally. My first experience was in AIESEC - international student organization. Later I learned by practicing. Schools and universities started to invite me for small speeches when I was 21-22 y.o.
The next level for me was the preparation for One Young World Summit.
Among the speakers of the conference were the co-founder of Twitter, CEO of Deloitte UK and blogger MamaBee. It was just a 5-minute performance, but the preparation was even bigger than for TEDx. I worked with a few professionals. In the audience were sitting a former president of Ireland, few Nobel laureates, Akon, Naomi Campbell, Queen of Netherlands, and 2000 other people. I truly understood the importance of professional preparation after I got a standing ovation for this speech.
