This quote comes from a different tradition than the meditation quote earlier, but is essentially saying the same thing. It is from Charlotte Selver, an extraordinary woman and one of the greatest influences on body-orientated psychotherapy today.  She lived a long life – was teaching still at age 101 – and  emphasized that we should being fully present in each moment, seeing it as completely new, being open to all the riches it could contain. This requires a full commitment, not standing on the fence, not watching the moments with tired eyes. She taught this by teaching movement in the body, being fully in touch which its action:

It is not first this, then this, then that – the whole person comes into motion.
There is nowhere where it stays as is, when I begin to allow movement.  

When you have to laugh, there’s nowhere where you don’t laugh.   Or you are only partly involved with laughing?
Nowhere, when you are crying, where it isn’t crying in you.  
Does that make sense?  
In other words, to give myself to something means not to go point by point.
