The devil's advocate internal monologue

My mind is fickle and flits from one point of view to another very easily. This is both a blessing and a curse. It allows me to see both isdes of an argument and therefore make informed assessments, but it also allows to do things I do not want myself to do or not do things I want myself to do.

Inspiration

A particular event, for example watching a movie, may inspire you to act in a certain way, but this inspiration wears off and you return to acting in your old ways. Is there a way of maximising the lifespan of the inspiration from an event?

Some events are once only, a movie may be inspirational once but has a lesser effect the second time. Is there a way of making events retain their inspirationality?

Is there a name for the study of inspiration?
