In "Pick one and own it", Jason Cohen advocates for picking just one advantage over your competition to sell, and really owning it.
Its a valuable debating technique to learn, regardless:? when confronted with an argument, instead of switching to a different argument, stick to the one at hand, and finish it out.? When you switch gears you're often conceding ground, without arriving at consensus. It also prevents you from being intellectually lazy if you can't just switch subjects when the discussion isn't going your way or the way you expected.
It is also a good way to build your brand if you can focus on just a few key advantages, taking each one to logical conclusion, instead of overwhelming the message with 100 advantages that are difficult to prove or show.
