In the doing comes the understanding. The wisdom of elder statesmen inspire and give hope. Looking back into the defects in step 4 and the 7 Seven Deadly Sins of pride, greed, lust, anger, gluttony, envy, and sloth.
It is not by accident that pride heads the procession. For pride, leading to self-justification, and always spurred by conscious or unconscious fears, is the basic breeder of most human difficulties, the chief block to true progress.
Pride lures us into making demands upon ourselves or upon others which cannot be met without perverting or misusing our God-given instincts. When the satisfaction of our instincts for sex, security, and society becomes the sole object of our lives, then pride steps in to justify our excesses. All these failings generate fear, a soul-sickness in its own right. Then fear, in turn, generates more character defects. Unreasonable fear that our instincts will not be satisfied drives us to covet the possessions of others, to lust for sex and power, to become angry when our instinctive demands are threatened, to be envious when the ambitions of others seem to be realized while ours are not. We eat, drink, and grab for more of everything than we need, fearing we shall never have enough. And with genuine alarm at the prospect of work, we stay lazy. We loaf and procrastinate, or at best work grudgingly and under half steam. These fears are the termites that ceaselessly devour the foundations of whatever sort of life we try to build. So when A.A. suggests a fearless moral inventory, it must seem to every newcomer that more is being asked of him than he can do. Both his pride and his fear beat him back every time he tries to look within himself. Pride says, “You need not pass this way,” and Fear says, “You dare not look!”

God, grant me the Serenity to Accept the things
I can,   Courage to change the things I can,
And Wisdom to know the difference.
