To learn, requires admitting you do not know as a necessary first step.
All my life I have found the best method of learning, to be hands on direct experience, or personal mentorship, rather than unquestioned acquisition of traditional theory and method, as useful as these tools are.
For me, the rigid school classroom of the 1980s seemed like an inadequately paced environment for one truly interested in the creative pursuit of knowledge.
What skills have been gained in engineering and Science here are largely self-taught, and what training I did receive was due to the generosity of those giants who allowed me passage up to their shoulders.
I strive to maintain the Humility required to continue learning, and not become mentally stagnant.
Problem solving free from fear of praise/blame dichotomy can be a path to skill.
Doing math and reading books is fun, remember? This is a non-monitized non-profit endeavor.
Goodwill to all beings on Earth and elsewhere.
Best wishes to all!
