Every single thought you have is a seed, planting a corresponding and related action that comes to fruition if nurtured and watered enough (with repeated, related thoughts).
Your words come from thoughts. So when you say things like, my situation is hopeless and I feel like a failure, you’ve planted and watered a seed of negative thought. When you write it down, you’re watering it again. When you your actions start to reflect these words, you’ve raised a full-grown living thing.
Every thought you have is either an investment or a cost. There is no neutral in the universe.
We know that trees and plants intake carbon dioxide and produce oxygen for us to breathe. The negativity plants that you grow are producing gases that will eventually kill you way before your time.
