Given the unfathomable size of our universe, the (more than likely) possibility of a Multiverse, and the accepted fact (or is it fact?) that we exist on earth for such a short period of time... it is foolish to place limits on anything - let alone our thoughts.
Every tremendous advancement, technological or otherwise, is made possible first through free and creative thought.
The most powerful tool we have access to is our own mind.
We spend our lives making products, and offering services other people have conceived and created. How many modern day Einsteins, Picassos, and Beethovens are tediously working in order to make someone else's dream a reality. What's worse, how many of these dreams are actually worth anything - in terms of the 'big picture?'
Can we agree our lives be much different today if Picasso had been (nearly) forced to choose between the fields of Psychology and Economics as his lifelong endeavor at the age of eighteen?
We are pigeon-holed by this societal expectation that we 'study' at a four year institution in order to reach optimum value.
There are a few problems with this expectation:
How much do students actually study?
Why must our method of learning involve having someone else walk us through a textbook, chapter-by-chapter, when we can invest in over 1,000 textbooks for the cost of this 'education.'
We apply the same expectations to every student enrolled. Where one student may excel, another might fall behind. This is understood by 4-year institutions, and the end result is an extremely slow method of content delivery, where no-one benefits. Teach yourself what you would like to learn, and do it in a fourth of the time!
Without time to explore your talents, and your passions, how will you even know what to study - at 18 years old - for more than $20,000 / year?
The biggest lesson these kids / newly anointed adults derive is that they have nothing to offer unless they have a bonafide receipt from an 'educational' institution.
When it comes to being equipped for the challenges presented to us in the "real world" - why is it that being "educated" is one of the precursors for anticipated "success"? Why do we not look for passion, likability, and humility as the most accurate signs that one may succeed, instead frivolous spending, unreasonable confidence, and the unwarranted sense of achievement that comes with exchanging $80,000+ for the most expensive piece of paper you'll ever buy?
This said, a message to parents, school teachers, and other key influencers involved with a child's development - sometimes if you recognize a Picasso sitting in your class, doodling "nonsense"... it may be best to just let them paint.
