Never say no to someone that is looking for a mentor. Most of the time, the limitation is not your time, but the ability of the protégé to consume the coaching and advice you impart. Almost always there is time between when you listen and share to when they come back looking for more. I also believe that it is the job of everyone to support others, regardless of their relative position in the community. Often people filter that they are willing to mentor, as to prefer only the absolute top talent. If we spent more time developing everyone, we might have better talent all around.
There is no shortage of ideas. This is one of those statements most do not agree with. Maybe we do not all come wired with this confidence, but I know it to be true. Being free with your ideas is the simplest way to enable the best thinking to flow into innovation. It also makes it irrelevant who owns which ideas – there are so many more it really does not matter. Secrets are the same way. There is no shortage of secrets to learn and sharing them does no harm.
Almost always, a protégé needs to have a certain level of experience to understand and make use of relevant secrets. It takes some time to make sense of the words you use or the situations you share. As a mentor you likely cannot practically compress everything for easy digestion. In fact, the simplest of lessons is often distilled to the point that it needs dilution. In the end, more often than not, the protégé is the gas pedal. When that pedal gets stuck, it will be your own inability to communicate at high enough bandwidth – help these folks get strapped to the fastest rocket ship you know.
People think that if they share what they know they will lose their power. This is the absolute wrong way to think about things. Creating a legion of individuals everywhere that grow to be giants is the ultimate in success and likely power. It transcends the walls of your organization and is the right thing to do for humanity. We need to take better care of each other.
