I don't get this at all.
WTF is "too ambitious"? When people *don't* want to make the only necessary "sacrifice" aka exchange/trade off? It's usually time that is otherwise spend on something else, which includes family, friends, other hobbies but the latter can be taken off the list because implicit to ambition is the higher priority of the thing or state aspired and worked on.
The ability to recognize quality grows quicker because of the amount of people who have successfully made the exchange and either improved their skill or found and implemented acceptable workarounds.
Most post-modern creation is fractal remixing. It's just effort put into time. The most untalented people can create superb stuff if they just keep grinding adequate levels of skill and workarounds.
The beauty, IMO, is in accepting the process of others and to support, motivate, inspire them, with anything one can provide. That will help them grow both, skill and taste, which in turn augments your world and raises your ambition.
Look at it this way: if you poison your neighbors you lower the quality in your environment which lowers the quality of your personal IO, input and output. You even lower the standards of the evaluation of your IO. Both, those of others and your own. You basically keep yourself low, and thus, your own creation. That applies to content, products, code and any writing.
People are stuck in the old hierarchical ways of thinking. That's not even annoying. Please hone your sense for quality. You don't owe that to the old world and guard but it would prove their effort was not for nothing.
