This thread is really good. Though I am also the victim of this but here are some I think will do good to someone.

1. Internet is the source of frustration,boredome,slacking and also can be the source of inspiration,good thing if we can use it efficiently. So, what I have decided to do is facebooking twice a day. @ morning while opening laptop and @night while sleeping. If you are tempted to see in between then just tell yourself..'Sunny if you see now then remaining time is 2-1=1". Also I get pretty much lost in footyroom, cnn,bbc,nagariknews,email etc pretty much. I am trying to reinforce it too. Just use laptop for work. Before to complete just one task(30 mins) it use to take hell 1-2-3 hours that was because in-between task ..we just loiter here and there in different sites but may be if we follow this rules, 30 mins task can take 40 or 50 mins max. I think.
2. Second thing I feel is comparing to others. This generates frustration,unhappiness etc. I think we pretty much know what are weakness within us and if instead we try to ammend it ,than that will generate much joy then trying to be someone.

p.s. I myself don't follow above things pretty much but am  trying to instead. I think it  might be useful for someone else instead :)
