It's true. Last year, in the annual race to the top of San Jose's City Hall (18 stories), I was 42 seconds behind the winner. At 62 years old I set myself the "impossible" goal of winning the race this year. By following these principles I have already dropped 43 seconds from my time and have a clear plan for dropping another 10 seconds before the race in October.
See your impossible dream, Understand its unattainable, Cry like the yellow bellied wimp you are, Crush your dreams of grandeur, Emit a wail of frustration, Suffer with the knowledge that others will achieve what you will not, Surrender yourself to despair.
fail.... actually visualizing that you achieved what you want to do releases dopamine in the brain related to the imaginative success and cuts your brainstorming some slack which in return weakens your enthusiasm for your goal thus minimizing the chance of achieving it for real ... umad?
I can't agree that we need to clear our minds of self doubt. Self doubt is a mechanism by which we may understand our weaknesses, which we can either work on or find a way around. Those with no self doubt are deluding themselves. We all have good reasons to doubt ourselves in one way or another. It's hubris to not and foolhardy, I think. Success comes to those who are not crippled by their doubt; who can learn lessons from it; who can accommodate it in their plans.
But what about all the people who try but do not achieve what they want to? Is there something wrong with them? The world is full of people who try very hard, who remain positive, who believe in themselves, who banish self doubt and they still fail. That's life. It's vast and complex and chaotic. It can't be boiled down to platitudes and acronyms.
