I asked, “Why do good cooks keep a clean kitchen?” And answered, “Because they don’t want the food they prepare to be spoiled.”
The human consciousness is like a kitchen environment.
An individual may have the know-how to do great works, but if there are spoilers in the mental environment in which he thinks, the chances of a notable outcome are diminished.
What are the spoilers? They are anger, resentment, ire, grumpiness, selfishness, lack of commitment, distraction, pride and their associates. These negatives kill the leaven, spoil the meat and sour the drink.
We need to keep a clean thought just like we need to keep a clean kitchen.
We can have the best of intentions, but if the mental environment we work in is filled with foreign agents working against out best efforts, the final outcome is in doubt and difficult to achieve.

Keep a clean kitchen today—a clean mental environment! And the tasks you perform in that workspace will turn out the best you could hope for.
