I guess I'm lucky that English is my native language because I'm certainly nogood at learning anything else. I've tried.

Globally - four most widely spoken.
Language Approx. number of speakers

1. Chinese 1,197,000,000
2. Spanish 414,000,000
3. English 335,000,000
4. Hindi 260,000,000

Then there's this
Second, there is no single criterion for how much knowledge is sufficient to be counted as a second-language speaker. For example, English has about 400 million native speakers but, depending on the criterion chosen, can be said to have as many as 2 billion speakers.

So perhaps you made a good choice.
And I'm doubly lucky.
Furthermore:
One of the most widely spoken and fastest spreading world languages today is English, which has over 900 million first- and second-language users worldwide.[3] It is estimated to have as many as 600 million second-language speakers,[3] including anywhere between 200 and 350 million learners/users in China alone,[4] at varying levels of study and proficiency, though this number is difficult to accurately assess.[5] English is also increasingly becoming the dominant language of scientific research and papers worldwide, having even outpaced national languages in Western European countries, including France, where a recent study showed that English has massively displaced French as the language of scientific research in "hard" as well as in applied sciences.[6]
so I'm triply lucky.
