If you become nervous, anxious, and irritable, you will damage the delicate fruit. Children must be handled with kind, patient, loving hands. As a parent as an adult you are still possessed of the natural passions and appetites that began even before birth. Your flesh lusts against your spirit. You know what you should do.
Conscience speaks with a voice louder than our excuses.
You may blame your parents for the bad programming. And they may well be the initial cause of some of your hang-ups. But you are now possessed of a mind and a spirit that is much the superior of your passions. Different from a child, you can choose to not yield to your weaknesses. Love of food, alcohol, and tobacco, or vanity of possessions, or bitterness of spirit may be more important to you than right doing, but you are absolutely free and able to step away from your early conditioning.
