Why do words get in the way?

Ever had to say something, but no matter how many ways you thought it through in your mind, you could never find the right words?

Some people have told me I talk too much. Some people have said they value wat i say, others think im full of crap (myself included).

then you could always say to me "tell the truth", "be honest", "keep it simple". but it aint always so simple to be honest and tell the truth. when a single misplaced word could really hurt someone (not necessarily me)

so i resolve to talk less.. and listen more. so that the impact/poignance of wat i say will actually be better than the random crap that i usually spew.

why have i suddenly gone into an introspective of myself? i dunno..

dang.. i guess its age.
