I'm definitely not breaking any new ground here...but this is something that needs to be said every so often.
Everything you're taught when you are learning ANYTHING, not just marketing or advertising, is to help you figure out what and when things need to be done.
What you aren't taught is NOT doing. These days too much emphasis is placed on putting out as much as possible as often as possible, no matter what.
Sometimes its better to not do something. I've been living that idea with this blog lately, because I've been trying to post something for weeks now, and I hate almost everything I come up with - therefore I don't post it, because I know not to - I have standards and a quality level in mind in regards to this blog, and I haven't been meeting it lately.
If you don't hear from me as often as you should - its because I know when NOT to talk. I do know when TO talk, but knowing NOT to talk is just as important.
