Path of Least Resistance?

I have often adopted the theory that what comes easiest, in relationship to my character and how I respond to others, is the natural or best way to be.  Upon reflection though, the path of least resistance is too often the path travelled by most.  Perhaps, like any rewarding situation in life, one's character, even at it's core, must be worked upon and challenged.  Strength of character and will are often products of hardship and testing.  Any sustainable relationship, whether it be romantic or platonic, takes work, deep consideration and is, above all else, a choice.
