I can face every obstacle that crosses my path.

Look backwards for a second at the ones already handled. The move you thought would break you. The week of phone calls about somebody else's paperwork. The diagnosis, the redundancy, the winter with no money in it.

None of them looked survivable in advance and every one of them is now behind you, filed under things that happened. Capability is nearly invisible from the front and obvious from behind. Today's is standing in the same position all the others once stood in.
