True. A person's relationships and environment can affect both the rate and the end result of development.
* **Rate of development**. The quality of a person's relationships and environment can have a significant impact on the rate of their development. For example, children who grow up in supportive and nurturing environments tend to develop more quickly and reach their full potential than children who grow up in neglectful or abusive environments.
* **End result of development**. The quality of a person's relationships and environment can also have a significant impact on the end result of their development. For example, people who have positive relationships with others and who are surrounded by supportive people tend to be happier and healthier than people who do not have these things.
In short, the quality of a person's relationships and environment can have a profound impact on their development. If you want to help someone reach their full potential, make sure they have positive relationships with others and that they are surrounded by a supportive environment.
