Many of my friends have been blogging for many days...some for many years (i guess). I have been telling them that it is a waste of time and it is not a really good idea to blog.But lately i started to realize that this is not a bad thing to do.So i have started to blog.I might not do this very nicely and i cant do it like the others are doing cause .........for real i dunno how to do this blog stuff. but i hope that i will get help form my friends and others and become a blogger who do a really nice and interesting blog!!!

So am really confused of this cause some have been telling that this is a bad idea and some have been telling it is really a nice work to do!!!
