The 90-10 rule can be the difference between having a life that's hard or joyous
What do we really control in our lives?

A woman is both happy and angry.
There is a psychological concept known as the illusion of control, which states that people believe they have greater control over the events in their lives than they do. If you think about it, a lot of our lives are controlled by chance, whether it's our genetics, the families we were born into, the time and place where we were born, and chance encounters that change the trajectory of our lives, such as the moment we met our spouse or someone with a job opportunity.
People who have it good are more likely to attribute their good fortunes to their effort, while those who are having difficulty getting by are more likely to blame bad luck. No matter how we delude ourselves, one thing is certain: many situations we find ourselves in throughout life are out of our control, and our real power lies in our ability to react.
Knowing how to react to situations beyond our control is the crux of the 90-10 rule.
What is the 90-10 rule?
The 90-10 rule, attributed to Stephen Covey in the bestseller “7 Habits of Highly Effective People,” states that 10% of life is made up of what happens to you, and 90% is decided by how you react.
People often explain the 90-10 rule by sharing a story of a mishap at breakfast.
You are having breakfast in business attire and your young daughter spills coffee on your shirt. You reprimand her and your spouse for putting the cup of coffee too close to the table's ledge. Your daughter gets upset and misses her school bus. So you have to drive her to school, and because you’re speeding, you get a $180 ticket. You arrive at work late and the day spirals from there. When you get home from work, you have an annoyed wife and child.
Why did you have a bad day?
A) Did the coffee cause it?
B) Did your daughter cause it?
C) Did the policeman cause it?
D) Did you cause it?
The answer is "D".
In an alternative universe, the coffee spills on your shirt, and you forgive your daughter. You change your shirt, your daughter makes the bus, and you get to work five minutes early. Now, instead of having a day that spiraled out of control, taking a moment to see the spilled coffee as an accident changed the entire day.
What happens when people skillfully respond to events out of their control over a long period? Their lives will be completely different than if they chose to take things out of their control personally.
Here are 3 ways to apply the 90-10 rule. The key is not to take minor inconveniences personally.

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
