In my opinion, there`s no such thing as a fear of the unknown. We use
the word "unknown" as a placeholder to mean "whatever is the opposite
of the known."
The way I argue the case is that you can`t have a "thing" that doesn`t
exist. You can refer to it, but it still doesn`t exist. Therefore
something else is causing the fear.
"Dark" doesn`t exist. There`s only the lack of light. We need a way, in
language (which drives our thinking and emotional responses) to refer
to that absence of light. So we call it "dark."
The "unknown" is either chaos, or lack of certainty---the known.
Your fear, then, is rather that you have a low tolerance for the uncertain. And your quest is for certainty.
The problem is that whenever you start something new, it`s almost
impossible to be completely certain of the outcome. That`s a function
of reality and life, complex systems, variables, chaos theory, and so
So: Examine your "need" for certainty, then take a look at your
risk-tolerance. If you`re not capable of, or have little desire for risk,
then perhaps you`d do better to invest in a business someone else is
On the other hand, if you believe you can change your level of
tolerance for risk, then the best you can do is extract those variables
with the highest certainty factor and focus on them. Isolate those
low-certainty factors, and spend your research efforts on seeing if you
can improve their level of certainty.
