I go a few past thirty and always try to exceed four lines. Anything worth doing is worth doing well and I would hate to have one of my posts rekected for being too short! Three bucks is three bucks and if I have invested any time into something I want to make sure that I get paid for it. Under promise and over deliver takes me pretty far in everything that I do and I am glad that my children have picked up on some of this trait. They work hard at school and gove their tachers more than they were asked to which results in great grades!
