Wisdom can be defined as knowledge in motion. When we know something to be true and are able to implement it in our daily lives, it turns from theoretical knowledge to practical wisdom.
At a personal level, wisdom is to continually bridging the gap between what you know about yourself and who you are.
And interestingly, you can close this gap in both directions – through addition and subtraction. You can learn more about yourself. At the same time, you can subtract everything you know that doesn’t make a difference to who you are.
Additive wisdom is fairly abundant. It is subtractive wisdom that is in short supply.
