I have heard about the concept of non-linearity. In the classes I take, we talk about letting go of control and how the world of energies is not linear. 

So some days, writing or talking about what I am grateful for is more difficult than other but then unexpected things are showing up in my life. For example, I was at work concentrated on the task at hand and out of the blue I felt a wave of happiness through my body. It was a wave so it came and went, but it has a lasting impression through the fact that it happened. It’s possible. It exists. 

I am grateful I got to experience this wave of surprise happiness for no reason.
