Imagine it's a hot summer day. The sun is shining, there's not a cloud in the sky and you are laying by the pool, looking all skinny and tan in your bikini. "Hmmmmm, I think I'm hot. I'd love to jump in the pool.," You think to yourself. So you saunter over to the pool and dip a toe in. Boy, it feels good: cold and refreshing. You know if you jump in though, it's going to be really really cold.
Do you jump in anyways and hope that despite the initial shock, your body will get used to the temperature and it will feel good?
Or do you stand there and wait for someone to come along and shove you in? After all, if it is freezing cold and you don't get used to it, at least you weren't stupid enough to jump in the water on your own. And if it feels good, then you thank the person and enjoy the water.
Or do you stand there in the sweltering heat because you are too afraid it MIGHT be cold, but maybe it won't be and you're missing out on a refreshing swim in the pool?
