Well said! Many things in this world require the use of the English language.
Imagine trying to become a respected diplomat, scientist, banker, economist, doctor, or senior manager in an international company without mastering English.
Those who master it have a significant advantage - an even bigger advantage than those who were lucky enough to be born English.
For the first time, ever in history, it is possible for everyone on the planet (except North Korea) to access free of charge all the books and lessons needed to master English. Many foreigners now speak better English than 70% of the population of England.
One very good place to find English lesson resources is the BBC.
Hahah yes after travelling for the past year I can second this...
I've met so many people on the road who speak English as a second or third language, and their understanding of the language surpasses many of those from back home!
I am learning Spanish and can actually say the same the other way round. Many times when I am texting Spanish speaking friends, my grammar is much better than theirs.
I guess sometimes we get lazy with our own native tongues and forget the importance of correct grammar, well-structured sentences and clearly presented layouts.
An important comment @crypto-wisdom - a very valuable addition to an already very useful post... thank you both!
