You can enter Peak State quickly with this condition:
1. You must relax first.
2. You must focus with one thing/think.
3. Your emotion must be connected with this think/think.
If you are auditory, better with affirmation technique. When you are kinetic, best with emotional anchoring.
You can choose one of them, or, you can use other technique that you like. The important point is you use technique that make you relax with fast, make you focus with fast, and make you enter your Peak State with fast too.
