How could our Heart's passion possibly not strike a chord within people? Our Heart is the place where we realize that all is One. So others will naturally feel the Love in the work.
Yet my point of view is nonetheless that a post that tremendously helps one single person has more value than one that reaches hundreds of people without any personal value to each!
Writing like you are talking directly with one person, makes people feel they are special.
The people who follow my blogs regularly become like friends to me. I really enjoy their input. They're great folks.
