The corridor principle experiment was conducted in a study done by Robert Ronstadt back in the 1980s. He explained the principle as the mere act of starting a venture in which enables entrepreneurs to see other opportunities they could neither see nor take advantage of until they had started their initial venture.
The difference between those who succeeded in the entrepreneurial field was because they took the chance to launch themselves even without the guarantee of success.
When we have the opportunity to take action towards our goals and expand our comfort zone in order to gain the knowledge necessary for us to pull through, we'll be able to improve drastically.
What we accomplish in our life always begins with our willingness to face the uncertainty of everything and be able to move through confidently towards our goal. So keep in mind that time and opportunity don't wait for us, we must take a leap of faith and take action for ourselves.
