Interestingly, that is the opposite of what I've seen in the scientific literature.

Trait self-control seems to better relate to removing temptations from our lives via planning rather than having a high threshold for resistance. People who identify as "having good self-control" tend to have fewer strong desires and weaker resistance. Tellingly, trait self-control also doesn't seem to change the relationship between resistance and enactment. So people with self-control are just as likely to succumb to temptation when it is present, but less likely to be confronted by temptation in the first place.

Check out Hofmann et al. Everyday Temptations for an example (2011).
