Both of these things are true. But can people make the forces we do not control work for us in business and life? Yes, according to an insightful and important book by Frans Johansson, 'The Click Moment: Seizing Opportunity in an Unpredictable World."
Here is the deal: If we do nothing, nothing good happens. For something to happen, one must act even if unsure where it will lead. I know, I know: This is hard to accept because lawyers have our goals, our marketing plans and our well thought out ambitions. But, as a famous boxer insightfully remarked, everyone has a plan until getting hit.
Johansson writes; “Once you start executing, whether or not the bet actually works in your favor, you are exposed to complex forces that can pave the way for future success. Even if you do not have a crystal clear goal in mind, it is still better to do something — and to tell people about it. The complex forces of the world will now have a concept to work with, and you will have exposed yourself to the possibility of positive unanticipated consequences, cascades, and self-reinforcing loops.”
To succeed more, try more. See rejection not as a "no" but as a "not right now." Don't think about doing an act, just act.
I did not always understand these ideas. But sometimes wisdom never comes, so we should not reject it merely because it comes late. Give the book a read. Five stars.
