While it is true that this is a thing that happens which can be very demotivating, for me i think the more demotivating thing is the idea that i'll do all this work writing stuff down, and nobody will care.

And unfortunately nobody caring is by far the most likely outcome.

I usually tell myself that my blog post is first and foremost for myself to better reflect and understand what i learned. That it is an end in itself and still worthwhile even if nobody reads it. Nonetheless i still find this the most demotivating part of keeping a blog.
