I'm attracted to the idea of producing content related to full stack development and/or gamedev (not that of my strongest point but I like to do that too) but something I cannot decide on is which language to target, as I'm a native Spanish speaker.

The only reason I see to do content in English is that it would reflect good on my CV and/or any future business opportunities, also that in regards to tech videos is what I watch on a daily basis as content in my native tongue is poorly produced and/or dated.

the only set back is that I suck a bit speaking English and my grammar sucks a lot, and that can ruin it for me.

what should I do?
