Hold on let me think..one thing I can't live with out? Is Knowledge.

One thing I can't go without is knowledge. 

Everybody knows that knowledge is power.

If we have knowledge then the world is ours!

When we leave this earth we can't take our phones, designer bags and fast cars with us 

But we can take our knowledge.

The one thing that no one in this world can steal from us is our knowledge. 

If I'm deserted on an Island with nothing but knowledge I will survive. Why?

Because I will have the Knowledge to develope skill and performance on surviving. 

If you really ask me, Knowlege is key. 

With knowledge you and me can be free.
