Well of course it is not enough. This is well known.
"Success" is hard to nail down. Is it academic success? SES succes? Job performance? It's all over the map.
However we know that :
IQ is correlated with the above somewhere between 0.2 and 0.5, with many definitions and studies being near the top of that range.
Conscientiousness is correlated with the above somewhere between 0.2 and 0.3, with many definitions and studies being near the top of that range.
Low neuroticism is correlated with the above somewhere between 0.1 and 0.2, with many definitions and studies being near the top of that range.
And there are other "personality" metrics that have been studied. It is very easy for someone who has an exceptional IQ to be sert back by neuroticism for example and exceptional IQ is near useless if the person does not have the conscientiousness to follow through on tasks, these people will likely be exceptional a "shallow" tasks.

I think this is well trodden ground.
