The world never stands stillâand medicine is no exception. New insights, research, and ideas pop up constantly. Sometimes it feels like what was true yesterday is outdated today. Some schools, teachers, and colleagues simply canât keep up. Thatâs why you still hear physios telling patients thereâs a ârightâ way to sit or lift, or insisting your knees should never pass your toes during a squatâeven though we know better now.
Ever watched a kid pick something up? They donât stress about the ârightâ wayâthey just lift in a way that feels natural for their body and the situation. So why donât we do the same? Instead, we overthink every move, afraid weâll break something. How are you supposed to walk down the stairs if your knees canât go past your toes? Or crouch to tie your shoes? It just doesnât make sense.
I finished school nearly two years ago, and even then, I was still hearing these outdated myths. I even passed some of them on to my early patientsâa mistake Iâm still a little ashamed of. But I quickly learned to question what I was taught because, honestly, thatâs the only way to grow.
A lot of people still believe these myths. Whenever I ask my patients why their back hurts, I almost always hear: âBecause I sit wrong,â âMy posture is bad,â or âIâm lifting the wrong way.â
Weâve spent years drilling these ideas into peopleâteaching the ârightâ way to sit, lift, and hold themselvesâyet back pain is still everywhere. The real issue? Holding on to old ideas messes with how we move and how we think. Instead of moving naturally, like a kid, we start overthinking every little move, afraid of doing something âwrong.â Clearly, somethingâs off.
The problem isnât just piling on new knowledgeâitâs letting go of old myths. We often think the more we know, the smarter we are. But real wisdom comes from unlearning just as much as learning.
Derek Sivers uses a great analogy: imagine a number line from 0 to 10. Youâre at 7, but you want to get to 4. Can you just add more? Noâyouâd end up further away. You have to subtract.
Itâs the same with knowledge. Sometimes, to make space for something new, we need to let go of whatâs already there. The real question is: how do we actually do that?
First, doubt everything you think you know. Seriouslyâquestion it all. Imagine for a moment that everything youâve learned so far might be wrong. That mindset opens the door to real growth.
By thinking this way, you build a growth mindsetâcurious, ready for challenges, and open to change. Learning doesnât stop after school; itâs a lifelong journey.
Second, stop pretending you know it allâbecause letâs be honest, you know nothing, Jon Snow. Try seeing yourself as a beginner, not the expert. Sure, expertise feels goodâit means youâve made it, right? But the âidiotâ in the room asks questions, listens, and learns. Isnât that the point? The moment you think you know everything is the moment you stop growing.
In the beginner’s mind there are many possibilities, but in the expert’s there are few.

And third, make sure what youâre learning is actually still true. If itâs outdated, let it go. Unlearn it.
The world keeps moving, evolving, changingâand we need to change with it. What felt right yesterday might be completely off today. Holding on to old, useless info just clutters your brain.
So go aheadâdeclutter your mental space. Make room for fresh, relevant knowledge. Out with the old, in with the useful.
đ§Ș Letâs Experiment
Letting go of old myths is just as important as learning new truths.
Weâve seen how clinging to outdated ideas can block growth. A simple way to start breaking free is to question one belief at a time.
đŻ Try This:
Once a month, pick a belief or âtruthâ youâve been holding ontoâespecially something about your work, health, or daily habitsâand question it.
Look up recent studies, listen to a podcast, or read an article or short book offering a different perspective. Ask yourself: Is this still true? Or have I just never questioned it?
Then, if needed, update your thinkingâor unlearn what no longer serves you. Itâs a small habit, but over time, it can seriously shift your mindset. Think of it as a monthly brain declutterâclearing out the outdated stuff to make room for fresh ideas.
đ§ Final Thought:
The goal isnât to abandon everything you knowâitâs to keep your thinking flexible, curious, and current. A little monthly questioning goes a long way toward staying sharp, adaptable, and open to growth.
Keep it simple, stay curious, and keep learningâyouâve got this.
Take care,
