The video was loooong ... but I wanted to tell you about my experience studying English abroad (particularly in Sydney).
Beyond studying abroad, online, in the classes that the company gives you as a benefit, in the institute of your neighborhood or in a self-taught way, do not stop doing it. It is an essential tool for those of us who work in IT. Especially for those who want to learn, grow and / or have international opportunities.
Hopefully it will inspire you!
