Is the statement “You just need to work on your mindset and your life changes forever” a lie? 

One thing that have baffled scientists is how the type of babble or gurgle of a newborn child would be different from another, depending on the kind of native language that their parents were speaking. For example, a Swiss baby would sound differently form a Chinese or American baby.
Science Daily revealed, infants start to pick up a characteristic of whatever their first language will be while still in the womb. What this study points out to is that babies opt to produce these particular patterns according to what they hear while inside the womb. These data maintain the significance of a baby’s crying in developing the skills for its specific language.
During the last trimester of the mother’s pregnancy, an unborn child is capable of memorizing a variety of sounds coming from the world outside the womb. The baby favors his mother’s voice from all the other noises and distinguishes the emotional substance, sent through the tonal forms in the mother’s speech.
It is truly an amazing thing to be able to understand how an unborn baby builds already patterns through experiences inside the mother’s womb.
Over decades of research, children development specialists have more than proven that the environment of a child’s earliest years has effects that last a lifetime.
The long-term effects of early stress, poverty, neglect and maltreatment are well documented and already an undisputed fact long before we could visualize them with brain scanning tools.
Why does it make sense to know the impacts of the time between conception and the current age of a person who asks for expertise? There are some good reasons why we should pay attention to the evidence provided by neuroscience. For instance, it may help us learn exactly how experiences affect a human’s life path. Additionally, this knowledge can assist our efforts to help people who are at risk and undo the effects of early adversity. Understanding these imprints and patterns delivers the marks on the life map (like a blueprint) of a person and facilitates us the tools needed for the TRANSFORMATION CODE, which improves greatly our attempts at intervention.
Between conception and age three, a child’s brain undergoes a massive change. It has already at birth, about all of the neurons it will ever have. In the first year it doubles in size, and it has reached 80% of its adult volume by age of three.
Important to know is that synapses are formed at a much faster rate during these years than at any other time. In fact, the brain creates much more synapses than it needs. At the age two to three, the brain has up to twice as many synapses as it will have in adulthood. This extra amount synapses will be gradually eliminated again. This process is called Synaptic pruning. It includes both, axon and dendrite pruning, and is the process of synapse elimination that occurs between early childhood and the onset of puberty in many mammals, including humans.
The answer why the brain creates more synapses than it needs lies in the complex interaction of genetic and environmental factors in brain development.
Genes do not design the brain completely. The genes allow the brain to fine-tune itself according to the input it receives from the environment. All experiences are perceived with the senses and reported on to the brain. This input stimulates neural activity. Speech sounds, for example, stimulate activity in language-related brain regions. The more often speech is heard the more often synapses between neurons in that area will be activated.
Repeated use strengthens a synapse and synapses that are rarely used remain weak. The weak synapses are more likely to be eliminated later in the pruning process.
And here comes the thing: Synapse strength contributes to the connectivity and efficiency of the networks that support learning, memory, and other cognitive abilities. Therefore, a child’s experiences not only determine what information enters over the senses to the brain, but also influence how the brain finally processes information.
Understanding this, shows how dramatically your environment has taught you from the very beginning which synapses you have to use and how all other abilities and options fell victim to the pruning process.
Early brain development is the foundation of human adaptability and resilience. On one side it is a beautiful mechanism and it comes with a flip-side of the coin.
The Flip-side:
Because experiences have such a great potential to affect brain development, especially children are highly vulnerable to persistent negative influences during this period.
The beautiful effect:
On the other hand, positive early experiences have a huge effect on children’s chances for achievement, success, and happiness.

Basic definition of patterning:
Patterning is the forming of fixed ways of behaving or of doing things by constantly repeating something or copying other people.
