A Nov. 1, 2026, Marc and Angel Hack Life essay describes 10 habits its authors say can undermine happiness, including trying to control the uncontrollable, dwelling on past mistakes and fearing failure. The article is personal-development advice, not a scientific study, and it provides no data supporting the headline’s “90 percent” figure.
Marc and Angel Hack Life published a personal-development essay on Nov. 1 listing habits the authors say can diminish joy, including resisting change, seeking control over uncontrollable events and comparing one’s life with other people’s. The headline refers to “90 percent” of joy, but the article provides no measurement, research citation or method supporting that figure.
The essay presents its list as advice rather than a report of new research. Its first examples focus on responses to difficulty: expecting life to unfold a particular way, trying to control circumstances that cannot be changed, and clinging to how things used to be. The authors recommend directing effort toward problems a person can address and adapting when a situation cannot be changed.
Other habits on the list are refusing to forgive oneself for past decisions, defaulting to routines or choices without examining them, and resisting new ideas or lessons. The article encourages readers to learn, ask questions, and treat mistakes as opportunities for growth. These are the authors’ recommendations; the post does not cite evidence that following them produces a particular outcome.
The remaining items concern pursuing short-lived satisfaction at the expense of longer-term priorities, focusing so much on others’ stories that one neglects one’s own, and fearing failure. The supplied excerpt ends partway through the ninth item, after describing unsuccessful attempts as possible steps toward success. It does not include the tenth habit or the rest of that discussion, so the complete list cannot be confirmed from the material provided.
Advice, Not a Measured Joy Score
The article may give readers a vocabulary for reflecting on everyday patterns, but its headline’s “90 percent” claim is not substantiated in the supplied text. There is no stated survey, sample, time period or definition of joy that would let readers interpret the number as a measured finding. It should not be read as evidence that these habits account for a particular share of anyone’s happiness.
The distinction matters because personal-development recommendations are different from findings established by a study. Suggestions such as reviewing routines or being more open to learning may prompt reflection, but the article does not establish that they work for every reader or replace professional support when someone is dealing with serious distress.

How the Essay Frames Its List
The source is a post on Marc and Angel Hack Life, dated Nov. 1, 2026, titled “10 Little Habits That Steal Your Happiness.” It opens with the idea that repeated behavior shapes a person’s life, then groups its advice around attitude, change, self-forgiveness, learning, priorities and fear of failure.
The supplied report is incomplete: it includes the first eight habits and part of the ninth, but cuts off before the list concludes. The provided material also mentions the authors’ book, 1,000 Little Things Happy, Successful People Do Differently, and their journal product. Those references are promotional context from the source, not independent support for the essay’s claims.
“You ultimately become what you repeatedly do.”

The Missing Tenth Habit
The supplied source text stops during its discussion of the ninth habit, fear of failure, and does not show the tenth item. It is not possible to verify the complete list or the remainder of the article from the material provided. The source also gives no evidence explaining the “90 percent” wording: its basis, population and meaning are unspecified.
The post’s recommendations are attributed to its authors. The supplied material does not establish a clinical or scientific consensus that these patterns drain a defined amount of joy, nor does it quantify their effects.
Full Source Needed to Verify the List
Readers seeking the complete set of 10 habits would need to consult the full Marc and Angel Hack Life post. Until the missing text is available, the final item and the rest of the ninth item remain unverified. Any interpretation of the headline’s percentage would also require a stated method or supporting evidence, neither of which appears in the supplied source.
