I felt the same as you Husky; I had a few days where I was questioning what I was doing. My revenue has taken a big hit.
However, I am still motivated. I enjoy producing new content; doing the research and then writing about a topic which I think will be useful to others whilst creating revenue. I enjoy analysing my stats, trying to decide which topics to tweak and which topics to target next. I enjoy seeing an article get its first 'like' 'tweet' or '+1'. I find this stuff addictive.
I enjoy the lifestyle passive income has given me; I will fight to keep this, I do not want 'a job'.
