The explanations for the things we do in life are many and complex. Supposedly mature adults should live by logic, listen to their reason. Think things out before they act.But maybe they never heard what Dr. London told me one, Freud said that for the little things in life we should react according to our reason. But for really big decisions, we should heed what our unconscious tells us.
Avoid stock expressions (like the plague, as William Safire used to say) and repetitions. Don't say that as a boy your grandmother used to read to you, unless at that stage of her life she really was a boy, in which case you have probably thrown away a better intro. If something is worth hearing or listening to, it's very probably worth reading. So, this above all: Find your own voice.
