I like this, I might steal it:
I read therefore I am.
I set a challenge of 25 books for the year (although I did start part way through the year). I know this is not much by some people's standards, but it was a challenge for me.
I should set this for myself too... I think I already read around 5-10 books a year but not all of them are long enough. And if it's just reading then I probably read from the internet posts what can be collected into thousands of books. but that's not a quality reading.
I was reading a few, and very haphazardly at that - leaving some incomplete, or getting distracted part way through them Occasionally I would find a gem that inspired me, and that has kept me going as a reader. But it never came easily to me. Until making a more concerted effort, and the Good Reads reading challenge helped with that.
And knowing that it helps my writing to read so much more is also good motivation.
