how to create a habit in a simple and easy way.

First, decide on the goal, the north, and the reason behind the habit, like health, finances, career, etc. Create a swarm of behaviors, then pick 3-6 new habits. (To choose your new habits, ask yourself this: "Do I want to do them? and they are efficient towards my goal?) Make them smaller, focus on the starter step, or decrease the time to do it for 2 minutes in order to make it smaller, choose a trigger, and tips to select the trigger: the trigger and new behavior must happen in the same place; it has to be similar to the new behavior in order to avoid task switching; it has to be a solid trigger; it can't depend on luck; you can associate the new behavior with an existing routine; and make it as specific as possible. After selecting the new behavior and the trigger, rehearse the new behavior/habit and celebrate yourself each time you complete the new behavior. Emotions create habits, so when you celebrate yourself, you enforce the new habit into your routine better.
summary:

1. Select the north.
2. Create a swarm of behaviors.
3. Select 3-6 new ones.
4. They have to be small, easy, and effective towards your goal. Focus on the starter step or decrease the duration to 2 minutes.
5. Select a trigger. It has to be specific, and it has to happen in the same place as the new habit. Avoid task switching/triggers, and the new habit and trigger must be similar.
6. Rehearse the new habit; the more, the better.
7. Celebrate each time you do your new behavior; emotions create habits.
