I found what really brings the world forward: perseverance resp. aggregation. This can be aggregation of knowledge, of tools etc.. Everything large or powerful is something aggregated that has been developed in many years. The whole technological culture of humanity is actually something that was aggregated over thousands of years.
Aggregation is actually much more important then ingenuity; or even, ingenuity is in many cases the result of unhindered intellectual aggregation, in the sense of being something acquired by people who have the desire and possibilities to always learn something new in a certain area.
So for a society it is much more important to create infrastructure etc. taht fosters unhindered aggregation (which includes collaboration, synergy etc.), than to invest in supporting the “highly gifted” people. The same applies to personal life: there are only very few occasions where an ingenious idea or even a decision makes a big difference; the most part is work, and work is only fruitful if teh results can aggregate to something good for one personally.
