In the spirit of the What is a Word™/Phrase™ series started by JLee, a special brand of Phrase™ and Word™ puzzles.
If a word conforms to a special rule, I call it a Fortunate Word™.
Use the following examples below to find the rule.
$$ % set Title text. (spaces around the text ARE important; do not remove.) % increase Pad value only if your entries are longer than the title bar. % \def\Pad{\P{0.0}} \def\Title{\textbf{ Fortunate }} % \def\S#1#2{\Space{#1}{20px}{#2px}}\def\P#1{\V{#1em}}\def\V#1{\S{#1}{9}} \def\T{\Title\textbf{Words}^{\;\!™}\Pad}\def\NT{\Pad\textbf{Not}\T\ }\displaystyle \smash{\lower{29px}\bbox[yellow]{\phantom{\rlap{rubio.2019.05.15}\S{6px}{0} \begin{array}{cc}\Pad\T&\NT\\\end{array}}}}\atop\def\V#1{\S{#1}{5}} \begin{array}{|c|c|}\hline\Pad\T&\NT\\\hline % \text{ MY }&\text{ OUR }\\ \hline \text{ NOW }&\text{ AGO }\\ \hline \text{ CAR }&\text{ OIL }\\ \hline \text{ SINK }&\text{ SAIL }\\ \hline \text{ REAL }&\text{ HOAX }\\ \hline \text{ NUTTY }&\text{ CHEWY }\\ \hline \text{ SHEEP }&\text{ GOATS }\\ \hline \text{ BLAME }&\text{ ACCUSE }\\ \hline \text{ EIGHTH }&\text{ FOURTH }\\ \hline \text{ GLANCE }&\text{ VISION }\\ \hline \text{ YELLOW }&\text{ ORANGE }\\ \hline \text{ PARCEL }&\text{ PACKAGE }\\ \hline \text{ PROTECT }&\text{ ASSAULT }\\ \hline \text{ CLUSTER }&\text{ COMPLEX }\\ \hline \text{ DECREASE }&\text{ INCREASE }\\ \hline \text{ EXERCISE }&\text{ FEEDBACK }\\ \hline \text{ TREATMENT }&\text{ OPERATION }\\ \hline \text{ PRINCIPLE }&\text{ PRINCIPAL }\\ \hline \text{ REPEATEDLY }&\text{ CONTINUOUS }\\ \hline \text{ CENTERFOLDS* }&\text{ SUPERMODELS }\\ \hline \text{ ENTREPRENEUR }&\text{ PROFESSIONAL }\\ \hline \text{ DISTRESSINGLY* }&\text{ UNFORTUNATELY }\\ \hline \end{array}$$ * These are Very Fortunate Words™

The puzzle satisfies the series' inbuilt assumption, that each word can be tested for whether it is a Fortunate Word™ without relying on the other words.
These are not the only examples of Fortunate Words™; many more exist.
