One post per day


Writing (and publishing) one post per day was the promise I had made to myself and as you can see in the blog archive I have succeeded keeping the promise for 22 days. However, I have begun to question myself whether it is appropriate? 
Am I missing the bigger picture? 

I mean -
I write everyday, that is good. But, sometimes I write even when I am tired just because I have to write. Is that right? Would that not bring down the quality of my writing?
Other than this -
Would writing short poems/posts per day, give me less time (or maybe break the thought process) for bigger posts/stories?

Right now, I am confused. Your two cents?
