Hey Jaja, try not to worry. You will pass the 100 threshold soon enough. And as Attila said, even if you are not at 100 by the end of the year, it doesn't mean you can't join the partner program as soon as you reach 100 in 2022.

Just keep writing the best you can, and reading other people's writing and responding to them.

I only joined Medium in July 2021. In October I earned over $300 and now I've got over 800 followers. Just keep moving forward and you will get there.
