The importance of variety is a key facet with regards to making something successful, according to Malcolm Gladwell in this choice happiness speech.
In today's society, the amount of variety offered to people can't be understated. When an individual is asked what they want, it's often that they will give you a predetermined answer that's based on their previous experiences. The truth of the matter is, people never know what they want according to Gladwell. Individuals won't be able to explain their desires to the fullest form.
Companies would often focus on universal groups when creating a product. Understanding variability is of exponential importance in achieving success. The diversity of humans is a facet that companies need to take notice in order for them to strive.
