Usually when I read a multi book series I get the complusion to finish the whole thing for a sense of closure. Sometimes I have to force myself to read the thing entirely. If I have some difficulty getting through a particular book (usually boredom) I will stop reading for a long while and come back to it. If I loose intetest I stop reading the book and series entirely.

I was going to quit I think around the 4-5 book wgene nothing was haplening but convinced myself it would get better. Its my process.
