It's clear by now, that attempting to be a real expert in any given field, requires a tremendous amount of time, dedication, studying and commitment.
You can be a "half"-expert in canoeing, or back-country trekking, or in off-piste alpine skiing,
it's quite easy to master a difficult skill like rigging a 15foot catamaran for sailing without rudders in 5 Beaufort on the North Sea,
or it's rather complicated, but not undoable to learn the soccer game rules and qualify for minimum tresholds as a certified referee.
These are skills that can be mastered, given time and enough experience, and of course mentors.
In reality, becoming a real, more than "half" expert in any given field, requires much more;
it's about failure, and willingness to fail,
it's about confrontation with your own limits and willingness to engage in trade-offs.
It takes patience, even more dedication, time (left alone) and a cunning sense of distinguishing what you really need to know, and what can be dumped without any risks of being defrocked as a fake....
We all spend a lot of time pretending to be real experts.
Now is the time to firm up, catch up to our qualfiications and speak the truth.
