Not sure anyone will learn all they need to know in one weekend (2 days) but if you go to any conference of any kind you will walk away with so much information you will be processing it for ages. Not that is a bad thing, but if you go to a conference be patient with the information you get and know it will process eventually.
So if you are at a convention or conference remember to take time to enjoy it all. Save the processing for when you get home.
Oh and if you are a the FPEA Conference this weekend be sure to stop by and meet all the great people at time4learning.com and time4writing.com
