Here's a foolproof method to get yourself an A+ marketing brain, without having to pay for an expensive education.
Finish at least one good marketing book every week.
If you're not currently an avid reader, this might seem like a big deal. It's really not very difficult. Many marketing books are short, to begin with. And nobody said you have to read words printed on the page-audio books count. Most audio players have an option to speed up the audio-meaning you can often finish a book in half the time it might normally take.
If you read one good marketing book per week, you will have read 52 of them at the end of the year. How many of your peers do you think do that? How many of your competitors? Exactly. A+.
