So that you can bring your desires, your beliefs, your thoughts and your actions into alignment.
Because there is a law of attraction and it’s working every moment even if you’re aware of it or not. Because your every thought, every word and every action is asking for something from the Universe/God/Source/Higher Consciousness.

If your desires, your thoughts and your actions are not in alignment, then you cannot succeed.
Defining desires is the first step. You should find out what you want in every area of your life. Then you need to define your beliefs to see if they are in alignment with your desire. If not, your beliefs will block your desires. Set new beliefs. Then you need to think according to the new beliefs that are working in your favor and are aligned to your desires. Every thought and every word you say must be in accordance with your desires. Your actions must also be working towards your desires.

If you want something but then you think you cannot get it, you already blocked it. Then you want it more because you are concentrating on the lack of it. This is not aligned. These are energies that are pulling in opposite directions.

Example:

You want love in your life but you think you’re too old if you are passed 30 years old and love is hard to find, good guys are taken, anyone who is available must have a huge problem. Then you are complaining to your best friend that love still hasn’t appeared in your life. These beliefs and the stories you tell are not aligned to your wish. Identifying these beliefs and then redefining them into “love is easy to find at any age, and there are so many compatible people and they are everywhere I go” and then you create the actions that are in alignment like attending events that your loved one would also come to. Choosing a side of the bed to sleep on and let the other one free, leaving room in your closet for your loved one’s clothes… - those are actions in alignment. You are preparing to receive your wish into your live because you are 100% sure you are getting it. And you are not blocking it in any way.

Like the classic example of ordering in a restaurant. You choose something in the menu, and when you are sure of what you want, you give the order to the waiter. The waiter does not judge you if you order something healthy or not, it will bring it to you (the Universe/God is neutral). Then you wait on your order without being frustrated that it doesn’t come, and you don’t go into the kitchen to make sure you get it and even try doing it yourself and start let the staff know by yelling your order again and again while you are there, actually you do everything to block them, trying your best to mess with the process. No.
You are waiting at the table, minding your business. Taking action like remaining seated, going to the bathroom to wash your hands, put a napkin on your shirt, And you prepare for the arrival of your order by sipping on some water, enjoying a conversation with someone or just scrolling on your phone. And you start receiving signs that you are getting your order. The waiter is bringing you drinks. And then a fork and a spoon. Maybe the salt and some oils. And you are sure. You are not doubtful. You are not thinking thoughts that it’s not coming. You are relaxed and prepared to receive it. Think of that state of being when waiting for something you want. 100% certainty. That is confidence at its best. What is not that, it’s not confidence. If it’s less than 100, then it’s doubt. It’s ok to have a moment of doubt, but see it, analyze why it’s there - maybe there’s an old belief that is creeping in, and correct it immediately with the correct thoughts. If doubt is in greater proportion than belief, than you are delaying the arrival as long as you are in this state. The more you delay the arrival, the more doubt creeps in. That is your own trap. Take responsibility for your desires, your beliefs, your thoughts, your actions and CREATE your own life so that when you get to the end of it, you are content.
