"Don't dwell on what went wrong. Instead, focus on what to do next." - Dennis Waitley

One of my favorite quotes as well

No-one wrote History tends to repeat itself, if we don't put a stop to people crediting supernatural forces with everyday occurrences it will just keep happening, we are in a technologically advanced age and no-longer need supernatural explanations, that sort of behaviour should have been left behind in medieval times.

In fact, history IS repeating itself everyday! Just one example of this are The U.S's laws, and some other government related thing.
