Personal observation:verbal phraseology to be firmed up(or modified)

I rewatched the video of my presentation at IITM on March 13,2018,with Ranjith and his students in the audience(Mohan as well,being much more voluble than is his wont 😆;I realize that he cleared a lot of doubts of the students by reinterpreting my slides smartly{{but this is what any presenter does anyway,so its neither here nor there 😅).I realized that I needed to(still have to) convey a greater sense of confidence in my presentations(or talks of any kind).About phraseology,I used a glut of the horrid filler "SO", which[to try and excuse myself]I am of the opinion that I've heard a lot of others use in their talks,but I will strive to eliminate from my speech,completely if possible !😎
