Push the Boundaries of Your Personality
Maximize your contributions in fulfilling new ways

When I was 16 years old, doctors told me I had a rare and catastrophic genetic mutation, one that would lead to cancers in multiple organs.
Within a year, I had lost all sight in one eye to large tumors. The doctors said I would almost certainly face cancer in several other places, from my kidneys to my spine. For someone born in my generation with this mutation, life expectancy was about 40 years.

Research has shown that we can deliberately push the boundaries of our personality and that doing so doesn’t take all that long. A review of 207 studies found that interventions designed to change specific personality traits yielded results within six months, on average. Which means there is no good reason to hold back from pushing yourself to move into a career you think you’d find more fulfilling but worry you may not have the right personality for.
All the personality tests I’ve taken over the years, for example, have labeled me an introvert. I don’t dispute…
