would be in a better mood. In conclusion, the physical environment one is in can affect that way that person reacts to new experiences, and can contribute to the development of the individual’s personality. Perhaps the most important factor in personality development is the aging process. Depending on one’s age and maturity level, new experiences are perceived differently, adding in different ways to the core personality.

For example, once a person goes through puberty, t...
