I felt horrible about my English before I started. For example, before a presentation, I spent a lot of time preparing, rehearsing, and learning by heart. And if a colleague asked a question, I got destabilized.
Now, I feel really comfortable to manage my teams in Asia & USA. I have a lot of vocabulary for my presentations, I have better structures, I can even make jokes in my presentations! I definitely feel different now that I did this program!
