Heraclitus said that no man ever steps in the same river twice. Not only does the river constantly change, so does the man.
Similarly, every time we read a book, we see something new. The book may not have changed, but we have.
As such, we should not hesitate to exhort our employees, over and over again, to do the right thing. Between the last time we’ve asked and now, they have changed, and so have we. This time, it will click for some of them.
And for others, it’ll be the next time.
Keep it up.
