He “has dedicated himself to serving justice in all he does, and nature in all that happens. What people say or think about him, or how they treat him, isn’t something he worries about. Only these two questions: Is what he’s doing now the right thing to be doing? Does he accept and welcome what he’s been assigned?”
Marcus, keeping it simple. Only two concerns matter.
Do the right thing right now.
And embrace what fate has assigned to you. Work with what is. There’s no use in resisting whatever got you to where you are now.
But you can use anything—any obstacle or seemingly undesirable circumstance—to prompt you to do the right thing right now and propel yourself forward.
