Perhaps the phrase most associated with the British royal family is its longstanding policy of "never complain, never explain." However, as the monarchy continually modernizes, that mantra may not be appropriate for the royal system of the future, The Sun reports.

Last month, after a tour of the Caribbean that many considered disastrous, Prince William almost immediately issued an unprecedented statement about the tour, saying, "I am not sure how much I can learn from this tour. Much can be learned"

. [One example is a statement that succinctly addressed media and public concerns about the Duke and Duchess of Cambridge's consecutive trips to Belize, Jamaica, and the Bahamas.

"William and Kate will modernize the way we work. It is a breath of fresh air," a source told The Sun. 'They were hurt by attacks that their Caribbean trip was reminiscent of colonial times. From now on, they will tear up the rule book and do it the "Cambridge way." We are trying to figure out what that would look like. I am not criticizing the way things were done in the past. But times are changing."

Sources say that William has drawn a blueprint for his future as king and believes that the monarchy must be nimble if it is to survive. This includes stopping "never complaining and never explaining," as seen in his landmark statement at the end of the tour. After the couple returned from their eight-day trip, William apparently called a crisis meeting with his entourage to address the forceful criticism.

"The prince thinks the days of 'never complaining' are over for him," a source told The Daily Mail via The Sun. 'He definitely won't be speaking out on a regular basis, but he thinks that if the royal family has something to say, they should say it.'

In addition to being more open and candid, the "Cambridge way" is more cost-effective and less rigid, with a much smaller staff of nearly half of Prince Charles' 137 people, and instead of long trips like last month's Caribbean trip, Kate's short trips, such as her recent two-day visit to Denmark, are included.

"He [William] listens to people very well. (He) has a very clear vision for the future."
