Somewhere a True Believer is training to recruit your candidate. He is training with minimal food or water, in austere conditions, training day and night. The only thing clean on him is his phone and his Web 2.0 gear. He doesn't worry about what workout to do - his ruck weighs what it weighs, his runs end when his Candidate is hired and the Hiring Manager's need is filled.
This True Believer is not concerned about 'how hard it is;' he knows either he wins or he does not. He doesn't go home at 17:00, he is home. He knows only The Cause.
Still want to quit?
Be extremely subtle, even to the point of formlessness. Be extremely judicious in how you communicate, even to the point of soundlessness. Thereby you can be the director of your relationships with you partners; Hiring Managers and Candidates.
Better stop short than fill to the brim. Over sharpen the blade, and the edge will soon blunt. Amass a store of gold and jade, and no one can protect it. Claim wealth and titles, and disaster will follow. Retire when the work is done. This is the way of your Hire.
With apologies to Lao Tzu and Sun Tzu.
