Working at Home is Sometimes Hard

Today I worked at my job for GoFluent which I work at in my home office. Then it was time to write for my blogs. Do you ever have a day where you just can't come up with something to write about? I me really how do some writers come up with their topics? I just sit here with a blank mind. Even now writing this I'm still blank. Is that writers block? I don't know but, sometimes this just isn't any fun and today is one of those times. Does anyone have any suggestions on how to come up with topics. I would love to hear how you do it.
