Disagreements are a blessing.
Disagreements mean you are wrong and you have an opportunity to learn and grow.
Or they are wrong and you have an opportunity to teach them.
Or, what happens 49 times out of 50, you’re both partially wrong and have the opportunity to teach each other and take a train of though and improve it beyond what either could do solo.
Embrace disagreements with humility and open minds. Who knows where you can go from there.
