First Congrats! Second, you are doing yourself the biggest favor ever. You are 27 years old and publishing articles, that matter to you and show your expertise. Which means, in a long run whoever comes across with your article finds you as an expert.
Appreciate the "money" that Medium paid, appreciate each follow, view and process - you will see the outcome.
And other than this, I can totally relate when it comes to be a writer when English is not your fist language. This is definitely my biggest Block. Although I have a SIGN next to my computer: "You are allowed to make mistakes, what matters is the message"
Keep on sharing and I keep an eye on your journey! ;)
