There comes a point, where you don't need more books - but practice and action.
At this point "just another copywriting book" becomes just that. JUST another book on a mountain of books you could spend forever trying to get through.
Don't get me wrong. You have to put in the time and effort.
You need to read the classics, and then you should pursue more information.
But know that you have a limited amount of time and energy for consuming.
And that your time is better spent pursing action. (Creating, contributing, etc)
Which means you should watch your "Marketing info diet" carefully.
However you should always try and maintain connection with the fundamentals.
I can't quote anyone specifically, (but I know many top writers have echoed this idea)
Instead of hunting down more marketing material. Make an effort to read the classics over and over again.
Sharpening the saw, so to speak.
Which is why for the past 2 years, there's one of the advertising classics sitting above my toilet. (Right now it's Breakthrough Advertising).
Whenever I'm handling my business, I'm truly handling my business.
Is it a little gross? Maybe. Does it keep my grounded so I don't stray from the fundamentals? Absolutely.
I'm sure most of you have your own ways of staying grounded.
Don't hold back, let's hear them.
