Running a four-minute mile is hard. Being happy is hard. But these are distinct types of “hard,” and remembering that truth is vital.
The first type of hard is Never Done Before (NDB). Even for the most adventurous, the most risk-loving, and the most challenge-oriented, unique difficulty accompanies first attempts. For as much as you may believe in yourself, and as much as you may possess a rich resume of success, an inner voice of doubt (IVD) whispering Yea, but you may not be able to do this will be waiting for you upon an NDB undertaking. There are some near-universal NDBs, like running a four-minute mile, but every individual’s complete NDB list remains unique. This helps explain why the same activity can be so easy for one person (non-NDB) and so arduous for another (NDB).
Another type of hard is Please, Do That Again (PDTA). Unlike NDB, you have indeed successfully done That. Yet, you remain skeptical about your abilities since you lack understanding regarding how triumph occurred – you feel “lucky.” Thus, a replication crisis grips you such that if you are asked to perform That again, IVD will appear whispering essentially the same message it gives for NDB.
