A large number of incoming Presidents seem to just do their own thing. They don't avail themselves of the enormous amount of knowledge provided by RI. The other group I see does use information presented, although they may only follow it loosely. The difference is one group has taken the time to absorb the information.
Watching all this I'm thinking the latter method is the way to go. The knowledgebase maintained by RI through various documents provides a framework on which I can build my Presidential year, and relieve me of reinventing the wheel.
A few years ago I was reading a history of music, the author observed that "In the 16th century the creation of the western musical scale and rules, didn't hamper the creativity of musicians, it unleashed an explosion of creativity. Composers no longer needed to worry about wolf tones and other problems, the well tempered musical scales resolved this for them" [1]
The Rotary body of knowledge is similar. Learning it, following most of it, means I don't need to reinvent the wheel. It also means I can avoid many pitfalls because others found them the hard way, and have passed on the collective wisdom of how to avoid them.
One of the documents I really like is RI's checklist for Presidents Elect. An important lesson from that is to get going early, immediately after the December vote that identifies your board. That contrasts vividly with the more common, wait until PETS to get going. I've also seen the advantage of this watching district operations vs club operations. Our DG's have all been really good at getting it together early.
