“Vigilance in watching opportunity; tact and daring in seizing upon opportunity; force and persistence in crowding opportunity to its utmost of possible achievement – these are the martial virtues which must command success.” ~ Austin Phelps
You cannot be vigilant if you are upset by your immediate circumstances or worried about what might happen in the future. You cannot display tact and daring if you do what you do out of fear or reaction. You cannot apply force or persistence in relation to the large opportunities if you’ve failed to martial your forces in relation to the small ones.
Success is optional.
