You shouldn't care about what's going on around you. You shouldn't care if something went wrong. In principle, you don't care about all the obstacles and difficulties that arise in your path. The path to your goal. You have a plan, you have workarounds, you have backup options and a couple of aces up your sleeve, for the most difficult cases. And if none of this is there, then you will definitely come up with something to move on. No one will take away the most important thing from you! It's yours... The inner core!
