Generally I'll listen to one before sleep everynight. Because I've done that for so long, whenever I get an "aha" moment about some insight or issue, I just think "I'll use a paraliminal to deal with that tonight." Then I make sure to ask/answer the questions (sometimes take a minute to journal them) so I can set a strong intention before listening. If I don't have any particular issue that comes up, I'll use a general improvement one along the lines of one of my life goals, like self esteem supercharger or personal genius. Lately, new history generator, both A and B have been a favorite.
