I'm assuming that you're asking how to approach the issue of knowing what to do but not being able to bring yourself to do it. If this isn't what you're asking, then feel free to reply so, and I'll go from there.

Generally speaking, this happens because the first step [toward whatever you know that you should do] is too big for your nervous system to allow you to take. You can solve that with a structured version of self-administered exposure therapy that teaches your nervous system to stop doing that.

There's a great handout on the topic from the University of Michigan here: https://medicine.umich.edu/sites/default/files/content/downloads/Exposure-and-Desensitization.pdf

For example, suppose you're having trouble bringing yourself to approach. Write down a list of a few things that are "in the direction of" approaching, and score them from 1 to 10 (with 10 as the highest level of anxiety) in terms of how anxiety-inducing they are. Maybe this is what you come up with for the sake of the example:

• Asking random old men what time it is - 2/10
• Asking attractive women what time it is - 6/10
• Asking random old women what time it is 4/10
• Opening a girl with something you learned from the Mystery Method - 9/10
• Imagining approaching a girl, she doesn't seem interested, and you say have a nice day and walk away - 1/10
• Going out in public, making eye contact with fat chicks and paying attention to their responses - 3/10
• Going out in public, making eye contact with attractive women and paying attention to their responses - 5/10

You take the things you came up with, and you order them based on how much anxiety they give you:

1. Imagining approaching a girl
2. Asking random old men what time it is
3. Going out in public, making eye contact with fat chicks and paying attention to their responses
4. And so on.

That list becomes your training program. Now you have a new thing to do (imagining approaching a girl) that you feel more confident with that you feel better about doing because your nervous system isn't freaking the fuck out when you think about doing it. So you practice that thing a few times a day for a few days until you get bored with it, which means your anxiety for that task has fallen to a trivial level. Then you move on to the next one.

So in this example, you start approaching old men to ask what time it is. You keep practicing doing that a few times a day each time until you get bored with that one too. Then it's on to the next one, and you repeat.

Overall, you make a list like this for each thing that you're trying to do that you can't bring yourself to do. You start at the first step for each thing, practice it until you get bored and just repeat the process on down the line. This systematically trains your nervous system to stop making you freeze up when you go to do the things you want to do.

Have at it.
