The simple pine cone on the ground seeks only reproduction of its species. Let it lie. This sentiment speaks volumes towards human interference with both human and the earth’s ecology (don’t do it).
By interfering with intrinsic growth processes great damage can be done. This applies whether the object is plant or animal. In the case of humans letting development occur naturally is the optimal approach.
Normal Growth
Normal physical or mental growth (aka natural development) in humans varies by individual. As we age, our chosen activities (both physical and mental) dictate the type and magnitude of personal development.
From youth to an adult much of our growth is a mix of pre-programmed genetic factors and our environment which can be largely manipulated by the adults around us.
As time goes on our ability to make our own development choices grows. However, even in adulthood, sometimes others try to direct and constraint our choices.
Helping Others Grow
If humans were mushrooms putting them in a dark room and feeding them shit would lead to sustained growth. Unlike mushrooms, people need light and opportunity to develop best.
Providing guidance coupled with an enabling environment will allow others to make choices that fit their needs and thus are more likely to lead to positive results.
Framing expectations and funneling the learning opportunities can restrict development and actually be detrimental. When assisting others with personal growth, share your knowledge, provide support and guidance but do not direct.
This approach may not cause mushrooms to flourish but it works wonders for humans.
