I believe people are much smarter than they think they are.
What stands in their way is intimidation.
We as humans are intimidated by what we don't know.
It isn't difficult, but it is scary when we don't understand it.
Once we get over the psychological fear of new things, we zoom into new knowledge.
And BTW, psychological fear is empty...never warranted.
My thinking is that to have success, one must have an objective. That is sometimes the hardest part. A person can study this stuff all day, but unless there is a tangible problem to be solved, all is lost.
So one must have a need, such as a sprinker timer, lighting timer, garage door closer if I forget, ......
Otherwise, if no problem to be solved, no gain from pursuing this.
I speak from decades of such experience and success.
I also believe that this thinking applies to everything in life. Sort of like teaching a man to fish vs. giving a man a fish.
One must teach oneself, but the harder part is knowing what to learn. To know that, one must know what problem needs to be solved.
