Efforts

Everyone in this world has something special like talent etc..

What if you honed your talent up with more pratice and learning.

Show your talent to people but don't show your hardwork and effort behind it. 

For example you're getting a great physique and showing it to others. What they'll think of you . They admire you .

But when you tell all your secrets to them and give them all the advice to get a body like yours. 

They'll get bored , one or two will take on the advice and become as your competitors.

Take your things seriously but don't show your hardships and efforts to anyone .

It shows weakness. 

Keep your surroundings unknown about you.

Sprezzatura - a person who doesn't show his efforts to anyone.

He the Sprezzatura.
