Constant, Craving

Words for when one just wants to sit still and have some certainty of what will happen next. But knows it isn't possible, or even desirable really:

All changes, even the most longed for, have their melancholy; for what we leave behind us is a part of ourselves; we must die to one life before we can enter another. ~Anatole France

The man who looks for security, even in the mind, is like a man who would chop off his limbs in order to have artificial ones which will give him no pain or trouble.
~Henry Miller

The only difference between a rut and a grave is their dimensions.
~Ellen Glasgow
