Our thoughts have the power to guide our actions. Do not give space to negative thoughts to languish in the deepest crevasses of your mind and dismiss it as a small insignificant moment. Just as a mustard seed is the smallest of seeds.
A mustard seed can grow into the largest of garden plants and sometimes into a tree. When you inseminate negativity in your mind, over time it will propagate and cause more harm than good. It will take more time to correct, than it did to sow the seed of negativity.
