It’s not like lifting. It’s more like going to the gym. At least with most titles.
But going to the gym doesn’t create muscles. Taking action in the gym does. Only if you use the equipment in the gym and start lifting you build muscles.
Let’s say you listen to Libertine and SSX. This alone will not bring women to your flat. You need to get active and start exposing yourself to women, start talking with them, perhaps study how to approach them properly. Then the subs can work it’s magic.
Action is key.
Not taking action can lead to serious recon because your subconscious is persuaded to change but is always confronted with no action and doesn’t see results.
A few years back, before ZP, listening times were hours. Some played the subs non stop ultrasonic, all day long.
But with ZP less is more.
It can be, that subs take their time, because they need to lay the groundwork. But generally speaking, action is the secret to success, not excessive exposure (not that I’m saying you aim for that).
