In many countries, it is common for children to be told anything is possible if they set their mind to it. In my opinion, this can lead to great achievements, but for the majority engenders feelings of inadequacy.
Some people benefit from a positive emphasis on effort and achievement. The best examples of this come from the United States where famously every child is encouraged to pursue their dreams, no matter how aspirational and unrealistic. Those who succeed serve as role models and evidence the efficacy of pushing children to try to achieve anything. For example, the number of successful entrepreneurs and artists who have left their mark globally from the U. S. A is staggering and includes figures like Steve Jobs, Bill Gates, Michael Jackson, Warren Buffet, and Will Smith. These people often give encouraging interviews where they reiterate the importance of having passion and grit to achieve transcendent fame.
However, the cases above are exceptions and considering them the rule only hurts the self-esteem of the general populace. When an individual is told they can accomplish anything through sheer determination and they then fail to become rich and successful, they have no one to blame but themselves. The truth about the connection between effort and achievement is more nuanced than the platitude typically supplied to children. There is a complex interplay between talent, effort, and luck required to produce great achievements and all high-achievers are subject to determining factors beyond simply hard work. Teaching children otherwise sets them up for self-doubt, disillusionment, and delusions of grandeur that will weigh on them throughout adulthood. Hard work is an essential ingredient but supposing it guarantees success will only lead to resentment towards oneself and others.
In conclusion, while teaching children that hard work ensures achievement produces great individuals, overall, it breeds insecurity. Parents ought to instead encourage a positive mindset with less lofty expectations.
