The choices that others make cannot negatively impact your experience unless you include them in your experience through your attention to them. Things come to you only through your Vibrational invitation—and they remain only by your continuing attention to them.
Your Universe is based upon freedom. Freedom for everyone to choose what they give their attention to, and therefore what they choose to experience. And your interaction with one another provides a contrasting basis that assures continual expansion.
When others achieve Vibrational alignment with something they desire, they in no way deprive you of your desires. If your time-space reality has inspired a desire within you, it is certain that your desire can be fulfilled, for your Earth environment has the potential of satisfying the essence of all desires.
