Gratitude is more psychologically related. When you give thanks for everything in your life you attract more of those things that you are trying to attract. It changes your mindset to think positive and when you feel positive then you are in a better state to attract.
In many of my pictures and videos i show gratitude for having those moments in my life as this gives me positivity mindset, makes me happy and that feeling right there helps me to attract whatever i am trying to manifest in my life.
So start showing gratitude. You will be surprised on the various things you have in your life that you should be grateful for but are not.
For me - I thank the universe that i woke up healthy and happy, that i got to see another beautiful day, for breathing in fresh clean air - that itself is so much gratitude right there.
So start making a list and thank the universe as you go through the list.
