Daneil M. Wegner, a former professor of psychology at Harvard University, separated students into two test groups and gave different instruction to each group.

In the 1970s, a rumor circulated in the United States that a fast food company made hamburger patties from earthworms. The company immediately advertised that its hamburgers do not contain earthworms, but the sales constantly plunged. It was because people who saw the advertisement were rather reminded of earthworms.

Experts advise that if you want to get away from bad habits or worries, you should not suppress your thoughts or urges but replace them with something else.
Everyone faces worries and concerns. Instead of being confined in disturbed minds and endless thoughts, raise your head and look at the sky, imagining the Kingdom of Heaven. Moreover, God is with us, and if we leave our worries to Him, He comforts our minds.
Cast your cares on the LORD and he will sustain you; he will never let the righteous fall.
(Ps 55:22)
