How do I stop being afraid to speak because of my accent?

You stay silent to stay safe, because your accent and your mistakes feel like they are on display. That fear is real, and it is heavy, and it is also costing you. Every time you hold back, the room loses what you actually think. Here is the truth: an accent is proof you can do something most of the people around you cannot. You are working, and thinking, in a language that is not your first. That is not a flaw to hide. The people worth working with hear the idea, not the sound of it. Start small. In your next meeting, say one thing. Not the perfect thing, just one real thing. Mistakes will happen and the world will keep turning. Each time you speak, the fear gets a little smaller and your voice gets a little more yours.
