Reasons for less output in work

What is the most stupid thing that makes u zero work.

1.Chatting.. so close all messengers (yahoo, gtalk, skype, MSN)
2. Mail box.. as many differnt mail ids of different servers u have, that much less work that you'll do..:) so better not to have any mail ID.. :) But will any s/w engr exists without using cellphone and mail checking and chatting.. :)
Last but not least is, e-news papers which have some stories in their weekly or daily pages..
Good solution given by my friend is to take a printout and read..How cool this is..
After all, Preaching is easier than Practicing..:)
