What is practical is what must be done to succeed at something.
IF you have "right" practice then you achieve good results.
Think of playing Golf. The right swing will achieve an accurate drive.
Morality, for example, is like that. You lie to people and they don't trust you. Why? Because you've violated a law of religion? No.
It is because you cannot be counted on. You prove your lack of trustworthiness by your action of misrepresenting reality. Truth telling is the sort of morality which is: merely practical. That is: it must be done to succeed at something: being trusted and included among your fellow man.
So, in short, life teaches us what is real. It takes an unwillingness to continue to fail at life to get our attention.
The rational thinker wakes up out of their Matrix-like stupor one day and asks themselves, "What is going on here?"
The definition of insanity is: Continuing to do the same thing and expect different results.
We begin our rational thinking when we first RE-EXAMINE our definition of words. Then, we RE-Examine all the contexts which those definitions affect.
Without accurate definitions we are in an illusory make-believe world where anything goes!
Take that word: Spirituality, as an example.
There is flesh and there is spirit. These are opposites. Flesh can't BE spirit. So, that makes the core idea of "spirituality" a counterfeit concept. It is an actor's hallucination that he IS the role he is playing---right?
Take each and every CONCEPT word you know and see if you can give a short definition. Quirky definitions divorced from reality spin you out of rational thinking.
We must operate on a sense of reality or we we deflect our intelligence to a will-o-the-wisp.
You can't play life deuces wild and win.
Whims are red flags! What is a whim? The strong urge to do something without being able to attribute a rational reason to that feeling!
Impractical ideas detached from reasons are the "check engine" light for your mind!!
What is KNOWLEDGE? :What is known in a particular field or in total; facts and information.
Practical knowledge is useful to actually DO something necessary.
Impractical knowledge is useless for anything but debates about illusory and imaginary constructs.
From the period of our birth until the time of our death a CLOCK IS TICKING.
Everything we achieve takes place in between.
We only ACHIEVE when we......"do".
Doing must be practical to achieve something lasting.
Look at what an incredible, time-wasting hot mess the "knowledge" of Jehovah's Witnesses has always proved to be!
Speculations passed off as irrefutable and absolute Truth failed time and time again.
Each generation stubbornly insists on imaginary events about to be proven real---only to die entirely wrong and defeated by worthless knowledge.
LIFE must be treated real--because it IS.
All the silly ideas and impractical "truths" are just so much time-wasted.
Unplug, turn off and tune out from impractical distractions and use the TIME you have left to achieve something REAL for your life!
