Would you rather be the hammer or the hand that holds it? Better yet, would you rather be the person telling you where, or how hard to hammer?
Marketing leverage is the key to profitability. Anyone can hammer nails (words) but the art & science of marketing isn't for everyone.
You surely resist the need to spend money on marketing or paying specialists to do what they do best -but that's exactly what marketing leverage is all about (use (something) to maximum advantage."the organization needs to leverage its key resources.")
In a connected culture where every nail counts, you'll get better results by not doing some things yourself.
