The Holy Ruzhiner Rebbe zy”a interpreted the verse in Tehillim (37:10) “In a little while, the wicked is no more; reflect upon his place, and he is gone.” This means that “in a little while,” - shortly after sinning - “the wicked is no more” - the person no longer wants to be wicked for he regrets his sin. Therefore, it is better that he "reflect upon his place” - he should think before he commits the sin, at the place of the sin - and then “he is gone” - he will not commit the sin at all.
