Halfheartedness
There are people who are always doing things halfheartedly; lukewarm is their life. They never achieve anything because they are always holding back. They never move into anything totally, intensely. They are always standing on the bank and thinking of the farther shore. Or even if sometimes they try, they are riding on two horses; in case the one fails, the other will always be there. They are riding in two boats. Their life is so divided that whatsoever they do they always do with a dividedness. And any flowering of consciousness is possible only when there is an organic unity in you.
-Osho, "Theologia Mystica, #1"
