“The first is competence. Be brilliant in the basics. Don’t dabble in your job; you must master it. That applies at every level as you advance. Analyze yourself. Identify weaknesses and improve yourself. If you’re not running three miles in eighteen minutes, work out more; if you’re not a good listener, discipline yourself; if you’re not swift at calling in artillery fire, rehearse. Your troops are counting on you. Of course you’ll screw up sometimes; don’t dwell on that. The last perfect man on earth died on a cross long ago—just be honest and move on, smarter for what your mistake taught you.”
