Luck just means you don&#x27;t know the cause behind an effect.<p>Attributing success to &quot;luck&quot; is therefore simply putting the conditions for success outside your locus of control.<p>Attributing it to &quot;grit&quot; or some other personal quality puts the conditions for success within your locus of control.<p>For many people (myself included), the latter philosophy is more helpful as it makes success seem more deliberately achievable. Combined with a strong sense of agency, this philosophy can imbue its proponents with more confidence than those waiting for &quot;luck&quot; to happen (or who have given up on it happening).
