Writing is easy to get into, you can just have a idea, a general idea or a ship you like, and then you write. It seems easy, because to some extent, it kinda is.
The problem is mastery.
When you get into writing, you just kinda write it how you know how to write, it works, but it's not solid, it's full of flaws, and doesn't feel all that smooth. The problem that most people who aren't writing don't see is that it's incredibly hard to master Writing, why? Because you don't know what kind of writing style fits you.
If you get into drawing, you see what others make, so starting out is hard. The end-game however, it's rather simple. Drawing becomes fun, you like doing it, mastery happens with time as long as you continue drawing and trying new things sometimes.
So I would say that although sure, Writing is "easier" then drawing at first, sticking with writing is the real challenge, because you perfection in writing is incredibly hard to reach, if even possible.
Random thought that I'm pretty sure is accurate, even though I don't draw so that was slightly just speculation.
