Lack of resources teaches you the importance of resources 

A lack of strength teaches you the importance of strength 

You’re never going to be truly thankful for something unless there was a time you needed it and didn’t have it

This just made me remember this quote 

"Hard time create strong men"
"Strong men create good times"
"Good times create weak men" 
"And then weak men create hard times"

If you look at the world today, how life is and the way the inhabitants behave you'll see the significance of this quote in almost every area of  life
