When you express gratitude you are setting the energetic expectation that everything will be in accordance with your likes. This energy attracts exactly that.
It is not so much about the gratitude but the “vibe” that you emit. Your “vibe” will be met with a similar energy.
If you cannot stay in gratitude at least stay in a good mood. It is always easy to switch one’s mood with thoughts of babies, with upbeat music and people.
Try to keep the “vibe” you would like to see in your life inside and the outside will surely match that “vibe.”
