More is caught than taught.
Allow people to ‘catch’ you.
I schedule formal times of mentoring where my key staff have an opportunity to ask me anything on any subject. In these times they ‘catch’ my values & opinions.
Of course this is not enough.
People ‘catch’ you during informal times. When you are working together, travelling together, having coffee … whenever!
They ‘catch’ your habits, your ways, your language.
And thus they develop.
