Publish, or be overwhelmed
A PSFK report from SXSW pointed to a remark by Henry Jenkins, co-founder of the comparative media programme at MIT. He's quoted as saying:
he always tells his children to monitor the amount of information they take in versus the amount they put out.
That is to say, if you're not reflecting and expressing your thoughts and opinions on the data that you're absorbing, you'll lose of your ability to absorb that information in the first place.
So, more than ever, writing - or speaking - your thoughts, for an audience of one, or a million, is the way to make sense of the world.
