Next time, when you bookmark/favorite/mailyourslef a link to read later, think about it for a second or two. Think whether you really would want to read it or do you think you’ll make good use of the link. Give it an effective quick thought, overtime it seems more like an intuitive response. If the answer is no, you may not read it later, do yourself a favour by not bookmarking that link.
It can be easily argued that its a trivial thing and doesn’t hurt much. I would like to counter by saying – overtime, accumulation of unread/unused links creates a kind of guilt of “not doing” things you “love/like”. This is not a social effect but a result of introspection. Also I strongly believe that this is an extrapolation of the core human behaviour, to keep things which are not required with an explanation of later use. In short its greed. No its not wrong to save things for future, but when you do give it a good thought and act.
Why is it that it is greed when it comes to money and not when it comes to reading/knowledge ?
