You are correct in that your perception can mislead you into thinking that something or someone is or is not the enemy or an obstacle. Just because you preceive them as the enemy or an obstacle does not make it so. Likewise, just because you do not perceive them as the enemy or an obstacle also does not make it so.
In short, it is what it is...mistakes and all.
In the words of the rapper, common, "for every left make two rights",
for the best we can do is all we can do.
Therefore, we can identify what we think or percieve to be the enemy or obstacle but at the end of the day, our actions, tactics, responses will be the determining factor of rather we obtain our goals or accomplish our objectives. If we misidentify potential allies as enemies or tools as obstacles, we will miss opportunities or make our success much more difficult to obtain. On the other hand, if we do the opposite, we will get the opposite result.
Error, is an unavoidable aspect of the human experience,
just as ones perception.
Remember, your retort regarding "utopia"...
My point was from the assumption that you have correctly identified the enemy or obstacle as such, your success or failure will not be based upon your ability to change or redefine the nature of that enemy or obstacle, but upon you ability to change or redefine your actions, tactics, and responses to that enemy or obstacle.
I may be wrong, but the above reads like a non sequitur...or an oxymoron.
However, the common denominator...the constant...is
change.
In any event, I pose an analogy in regard to the above:
An enemy attacks you, and you fight them off...beat them
down even, they will, assuming they are sane, at least think twice
about messing with you again, or change up their approach, if not, outright leave
you alone for some time to come or kill them dead. Your 'success', their 'failure', ultimately
changed that enemy and obstacle it presented to you.
Full Speed, as you know by now, we don't live in a vacuum.
Everything affects everything. Everybody affects everybody.
Even your coughing affects the atmosphere, in some way, that I live in,
and will for a long time to come.
