The problem is we all think we are brilliant
All you can go on is the stats which show a marked increase in accident rates for single pilot ops in jets.
The other point to consider is that the owners spend a fortune on two jet engines, back ups in case of a failure but some are happy to go without a backup for the solitary pilot.
I know of one pilot who flew single pilot all his life until insurance demanded a full crew. He blacked out over Europe not coming to until the co landed and medical attention arrived. That was food poisoning.
