Buckminster Fuller may have started the self-help, PMA (positive mental attitude), and business consulting industries, and he is the mentor of many modern management and leadership gurus. 

He doesn't get the full credit for all he did because almost everything he wrote was extremely deep and, frankly, difficult to understand. 

But he understood how to solve problems.

He is said to have taken a year off work to sit on his couch and try to figure out the purpose of his career life. When he got off the couch, he literally changed the world.

Albert Einstein had a similar impact on the modern world, and he is another great thinker whose writings were difficult for most readers to grasp. 

And like Fuller, he knew how to tackle and solve problems.

Here then is advice on solving your biggest problems from two great masters of unraveling difficult challenges:

"It's not that I'm so smart, it's just that I stay with problems longer."  

-Albert Einstein

"In order to change an existing paradigm you do not struggle to try and change the problematic model. You create a new model and make the old one obsolete."  

-Buckminster Fuller
