Positive and negative are energies

They co-exist. Positivity invalidates nothing. Warmth is more like a product of positivity, no? You failed an exam and someone offers you an icecream to make you feel better. You can either be positive about it and be like "This might make me feel better. At least my tummy's happy." Or be negative and go "It's only icecream. I won't change a thing." You can feel warmth because you choose to be positive about it. It's your choice which energy you want to flow in your life.
