Blogging: How Do You Keep It Fresh?

As I "work" the internet to promote my ebook, A SPY AT HOME (available on Amazon for only $1.99), I see the hard work other bloggers do to keep up with those who follow them. It's amazing to me. When do they find the time? I have a full-time job and a family, and between that and promoting my ebook, revising the next one I will release - HAZARDOUS CHOICES - and trying to keep up with such things as yard work, etc. around the house, I'm exhausted!

Blogging is interesting. It can either be much like having a conversation with yourself, or it can be like talking to a (admittedly absent) friend. Sometimes the comments I post draw responses - occasionally heated ones - but other times the blog posts just lie there. I am not sure how a blogger draws the interest of blog-readers, and I would be very interested to know how some of the more successful bloggers keep readers tuned in to their blogs day after day.

If you are a successful blogger, please offer me some suggestions for keeping my blog fresh and alive. I'd appreciate it!
