The first rule of manifestation
For me, it starts with my morning routine
How you start your day is so important and if you start it by switching on the news you are beginning your day at a pretty low vibration. Even if it's just a habit and you're not really listening, you are still absorbing those lower-level frequencies.
Instead of the news, I started listening to podcasts which lifted me up and educated me, and I listened to music in the car rather than the radio. If you want to know what's going on in the wider world you can quickly catch up with the headlines later in the day.
The universe responds to your energy, not your wishes.
