One of my favorite blogs online is The Art of Manliness. They go through so many applicable lessons for today's Gentlemen from Relationships & Family, Manly Skills, and Dress & Grooming.
The latest entry I read was on The Law of Sacrifice. This article explains that attaining goals, and effectively changing one's self requires a price. As I continue through this project of recording my changes it was very helpful to be reminded of this law that this undertaking takes real work and fortitude. So I'm taking a card from the Gentleman's deck on this one.
