GM, it's not the best book but it's honest work. What matters though is consistency.

The hardest part about philosophy is to remember in daily life what you once understood during a meditation. On the spot, within a second or two, when life challenges you, to be able to recognize your emotions and to remember what you've once read and decided how you would act. The hard part is not understanding, it's acting on it when you actually need to. Even a child can understand it because what's good is often simple, even trivial.

The only way to get there is through repetition. Do philosophy every day and your moral instincts will grow like a muscle.
