I prefer to focus on qualitative goals, choosing different categories like one year I focused on reading more books by women, one year on books in translation, etc. I find it more motivating just having a framework to use to narrow down what books I’d be interested in, without sticking to it exclusively or getting worried about falling behind.

If quantitative goals are what work for you, maybe set a goal slightly below what you normally read, so you still have a number to work towards, but with less pressure? Tracking by page number also makes sense—I think Goodreads can do that.
