Self-comparisons are normal, but not always healthy.
For some people, success comes early and appears to be easy. Some tech entrepreneurs become billionaires in their twenties. Often, entertainers become famous and wealthy as children. Athletes become millionaires in their late teens and early twenties.
Measuring our success against the success of these people is flawed. Everyone starts from different places and with different opportunities. A better measure is how we stack up against our personal and professional goals.
