I know what it's like to walk back to your seat ashamed.
I was diagnosed with ADHD as a kid and could never quite regulate my emotions. Fight, flight, or freeze were very familiar to me. It was not only hard for me to express myself. In front of larger groups I'd mumble, stutter, forget what I wanted to say, go red, feel ashamed and sit back down disappointed in myself.
That followed me into adulthood, all the way to presenting at Ajax Arena and Pathé Tuschinski for work. My presentations were boring, with no story and no engagement.
Fed up, I joined a communication and leadership club called Toastmasters that was down to six members and nearly folding. Within 18 months I'd grown it to 24 and became president. Turns out I wasn't missing talent. I was missing the knowledge, the skill, and a few real wins to build on.
I'm here to tell you that this is a skill that anyone can learn. If an ADHD kid who used to freeze in front of his class can end up loving public speaking, so can you.
