maybe The BEST capability is The Imagination . . . .
it makes everything possible .you imagine ==> want ==> plan ==> program ==> make tasks ===> exercise /train/work and study Harder than yourself/the enemies ==> become the BEST in dealing with odds == > imaginations become real .
creation in acceptable ====> great levels .
therefore ,as HapPy says , its a rule :
Leave nothing to Imagination .
Nothing is enough except Darkness .
