We live in a world where everything is vibrational. That's how the Law of Attraction works: like vibrations naturally magnetize to each other. It's really quite simple. If you don't like what you've been attracting, change the vibration you're emanating.
To shift your vibration, alter what you focus on, what you think about, what you give your time and attention to. We modern humans have fallen into the habit of rampant negativity, but we always have the power to choose. I highly recommend opting for the A-list by appreciating anything you possibly can, accepting and turning your attention away from stuff you don’t like, and lightening up by being amused whenever possible.
