A professional boxer told you many things about how to become a great fighter — just like him.

But then you forgot most of the details even a few minutes after your conversation. And now you’re wondering why. Even worried about your poor memory.

Truth is, unless you’re planning to become a professional boxer, you need not to worry about forgetting it.

Of course you’ll forget! You’re not a professional boxer. Not even planning to become one.

What you heard from the boxer doesn’t matter to you.

The only knowledge that will stick to you is something that you truly need right now or in the future.

If it’s not a necessity, you’ll just forget it.
