It is easy to project your change within others ignoring the fact that it is within you and not them. Just because someone who once gave you their time gets occupied with more things that sets them to reach their purpose does not really indicate they’ve changed. What that shows is that they now know what they want and how to go about in achieving it. Stop negatively impacting them by leading them to question or doubt their purpose. If you wish them well then acknowledge that the change can also be within you.
