Willpower is the inner strength to do the hard thing and skip the easy one. Sheer willpower, lack willpower, test of willpower.
Research has moved away from treating it as a fuel that runs out: what looks like exhaustion is often a shift in what somebody wants to do. The practical finding that holds is that arranging your surroundings beats relying on willpower — people who avoid temptation succeed more than those who resist it.
