Representing the company – only 4x per year in English – feels blocked – wordfinding slow – eloquence missing

You do high level work and easily and eloquently present it in your mother language?
But four times a year you have to do this in English? And then you feel like blocked, you cannot play with the words, they don’t seem to be coming, at least not as easily and freely as in your mother language?
Do you feel like you have to run a marathon without any run to warm up or train before?
