There is no loss of effort on the spiritual path, the same cant be said about other effort in the world

This desire [for Bliss] is born of the sense of incompleteness. To whom is this sense of incompleteness? Enquire. In deep sleep you were blissful. Now you are not so. What has interposed between that Bliss and this non-bliss? It is the ego. Seek its source and find you are Bliss. https://www.speakingtree.in/speaking-tree/spiritual-thought/ramana-maharishi_38170
