🇬🇧 English isn’t my first language. Anyone else?

I’m active here, and English isn’t my first language.

It’s actually interesting that the whole global community of builders, makers, and founders has basically one common language: English.

And sometimes I wonder: how good does your English actually need to be?

I definitely overthink it sometimes:
Is this sentence natural? Is my grammar okay? Will people understand what I mean?

Maybe it doesn’t matter that much if you have something worth sharing.

So, if English isn’t your first language:

Do you ever feel insecure about your English when posting or commenting here? - and I’m not even talking about actual conversations, calls or meetings =D

And do you use AI to help you write, or just write and hit “post”?
