I have noticed that some folks go through periods where they stay on mission better by not sharing too much. The more people know about what you are up to, the more they tend to want to rock your boat, sometimes. Sharing what you have learned can be an act of mercy in a world that is always teaching you. Sometimes we really can't afford to share, and sometimes we can hardly afford to keep it all to ourselves. Seems to depend on the internal evolution and external currents.
Happy New Year
