Step 2 to mental strength

Step 1

After you have that freedom of the mind to consider all the variables that affect results and managed to weed out the irrelevancies. And you are able to hold them. Hold all the variables without dropping the ball. Giving each variable its proper weightage in your considerations.

Then the wheel meets the floor. At that time you have to do. And that is when many will falter. When their courage will fail them.

So this is not easy. But that GM will come from there. Do think on it at least. Give yourself that much freedom.
