Positive psychology expert shares how her simple 'Monday Math' can help you live your best life
It's a positive wake-up call.

It can be frustrating to feel motivated enough to pursue your dreams when your life is already packed with responsibilities and you have a limited amount of energy and attention. But we all have those things in life we’ve always wanted to do, such as learning a skill, traveling, or becoming more physically and mentally fit.
Jodi Wellman, who has a Master’s degree in applied positive psychology from the University of Pennsylvania and founded Four Thousand Mondays, coaches people on how to be more motivated by facing their limited time on Earth.
The concept may seem a bit morbid initially, but she says that when people honestly appraise their mortality, it’s great for long-term motivation. “My top tip is to get granular with what I call mortality math,” Wellman told CNBC Make It. “So we have to get really in tune with the temporary nature of our lives ... because otherwise, we won’t take action, we will languish.”
Wellman has a calculator on her site that shares the number of Mondays you have left based on current life expectancy. (The following is a calculation for a 47-year-old man.)

Wellman believes that when we truly understand we can only put things off for so long, we are more likely to follow our passions. “Later is an elusive time that may never come,” Wellman said. It’s also worth considering that some of the Mondays come when we’re older when it's more difficult to travel or do things that require physical strength.
“If you were going to die tonight, what would you wish you had taken action on? Maybe there’s an opportunity to start that today,” she added.
Mondays help put our lives in perspective. For many, it’s the first day back at work after the weekend, when it's time to get back on task, make new plans, start a new habit, or take on new responsibilities. Knowing there are only so many left can be a great motivator.
Wellman’s Four Thousand Mondays philosophy is based on the psychological concept of temporal scarcity, which states that it can be challenging to find joy in some of life’s pleasant experiences unless we know that they will come to an end.
It’s also based on the Freudian principle that we tend to seek pleasure and avoid pain and we will go to great lengths to prevent momentary pain. This can hinder us from pursuing our dreams which might involve a bit of initial discomfort.
By counting the number of Mondays we have left, we can avoid having painful end-of-life regrets when we realize that time is running out on our dreams. Wellman hopes that her philosophy provides a wake-up call for people to start living the life they always wanted because it’s later they think.
“We can fathom our deathbed regrets, for example, to sprinkle that dose of ‘oh sh**’ we need to take action in our lives,” she wrote on her blog. “We can focus on our limited lifespans and live with verve and vigor, to avoid the pain and heartache of a lackluster life we didn’t try hard enough to enjoy. In short, we will brazenly embrace the dark side… like a sneaky shortcut to the bright side.”

There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
