The key idea here is that monetization, regardless of when it is introduced, will slow down the other three gears. If you invoke too early or too swiftly, it is like popping the clutch on a manual transmission—you stall the engine. The art instead is to feather in the monetization gear in such a way as to minimize and absorb its retarding effects, ramping the engine back up to full speed over the least amount of time possible.
