Tired, exhausted, hurt, unmotivated, low energy and all the other B.S. An individual with true discipline will do what needs to be done no matter the situation.
Who you were doesn't dictate who you will become. It's called the past for a reason. You've already triumph and moved "past" that struggle. Only look back in glory ...and not in self doubt.
In battle, if everything is going according to plan, you're walking into an ambush. There WILL be hardships. But that's when the greatness within you arises.
