Back And Forth

I belive everyone needs some sort of consistancy in their lives...something however small that stays the same and acts as a grounding point for the spirit. That thing can be almost anything positive...a relationship, a job, even a hobby. Without some sort of positive grounding point we tend to just drift back and forth in a mire of confusion.I like this concept and I tend to agree with it. However what happens when your grounding point loses it's consistancy or it's stability? For example, what if the relationship is solid one day and unstable the next? Or I the job tends to go from good to bad then back again on a fairly regular basis? Does that inconsistancy then become your constant? If that's true, can we can assume that someone with unstable grounding points will become unstable himself, or will he adapt and look inside himself to stay grounded and focused using sheer will?
OK now I have a headache! Way to heavy this early in the morning....but interesting don't you think?
