The 90/10 Principle by Stephen Covey

Hey, check this

10% of life is made up of what happens to you. 90% of life is decided by how react. What does this mean?
We really have no control over 10% of what happens to us. We cannot stop the car from breaking down. The plane will be late arriving, which throws our whole schedule off. A driver may cut us off in traffic. We have no control over this 10%. The other 90% is different. You determine the other 90%.

Watch out for the next phase...
