It’s silly to think that you will always be right.
For one thing, life would be pretty dreary if there was nothing new to learn and surprise you. For another, you’d find that nobody would want to be around you for long.
It’s far better to keep an open mind and remain teachable, even into your wiser and older years.
Remaining teachable keeps things fresh, actually keeps you young and thriving, and has a great effect of bringing true wisdom.
You can’t always be right, but you can forever remain teachable.
