why not blogging?

This question pesters me a lot. Actually i started with the question, why blogging? you may not get time for writing especially when you are deeply involved in work or not good in writing or not interested.. i belong to the second category. Slowly i moved from 'why blogging' to 'why not blogging'. This happen to everyone's life whether it is about blogging or about shopping or about chosing profession or about .... but at one point all should take a decision of why not.
ohhh it looks quite philosophical... sorry people...
i am interested in sharing some stories and myths: mainly from my life and my place...
