This is from Steven Pressfield’s book, Do The Work
Stay Stupid
The three dumbest guys I can think of: Charles Lindbergh, Steve Jobs, Winston Churchill. Why? Because any smart person who understood how impossibly arduous were the tasks they had set themselves would have pulled the plug before he even began.
Ignorance and arrogance are the entrepreneur’s indispensable allies. She must be clueless enough to have no idea how difficult her enterprise is going to be – and cocky enough to believe she can pull it off anyway.
How do we achieve this state of mind? By staying stupid. By not allowing ourselves to think.
A child has no trouble believing the unbelievable, nor does the genius or the madman. It’s only you and I, with our big brains and our tiny hearts, who doubt and overthink and hesitate.
Don’t think. Act.
We can always revise and revisit once we’ve acted. But we can accomplish nothing until we act.
