A sapling grows the way you bend it.

You must start training your children one year before their first birthday, because if you don’t, they will be trained without your input. A sapling grows the way you bend it. But if you don’t bend it, it will grow and take shape just the same, though not as you would have it. It will be shaped by the prevailing winds, which, you can be sure, never blow in the right direction. 

From day one, every conscious moment of a child’s life is training; every event, and non-event, is schooling, preparation for the rest of life. If a child’s eyes can see, tongue can taste, nose can smell, hands can feel, or ears can hear, training is in progress. Parents don’t need to initiate a program, set aside a time, or confront the child in some special way for training to occur. Training and schooling never cease, never rest. A child develops with or without you. If you are not deliberately leaving your imprint on every stage of his development, know that someone is. [Source]
