I have always, both before and after being a Christian, found it easy to know that I was doing the wrong thing (and, to a lesser extent knowing what I shouldn't do) - but very bad at discerning my proper future path.
Although I have known plenty of people who mapped out their lives and stuck to, and sometimes accomplished, their plans - I always thought they were making a serious mistake.
Nowadays I regard my inability - my personal deficit - as (through no virtue of mine!) in accordance with the real nature of the human condition.
We are supposed to be committed to those we love (at least, within the inevitable constraints of mortal life), but beyond that we sin by living for our future planning - and this is indeed one of the cankers poisoning the heart of human civilization.
Something maybe inevitable but a necessity we ought to repent rather than praise.
