my wife just landed a confirmed offer at a tier 1 international school in singapore ($100k+ package)
she is french, but teaches entirely in english. tier 1 schools almost exclusively hire native speakers from the UK, US etc
when we met 8 years ago, she could barely hold a full conversation with me in english
instead of complaining about the odds, she went to work - she spent past 4 years refining her english and mastering a british accent until she could code-switch effortlessly
today she got the offer. a reminder that you don't wait for permission to be great - you build the skill, take the leap, grind for it and force the world to recognize your value
