Create a strong desire for your goal

To realize a goal, the goal can be wealth, a girlfriend/boyfriend, or a better living environment, a skill, etc.
firstly, ask yourself, in your heart of hearts, do you desire it, for example, do you desire a girlfriend or boyfriend? Strangely enough, you say that you want to realize a goal, but you may actually not desire it in your heart of hearts, because when you say that you want to realize a goal, you actually mean that you should realize that goal, but actually you don't desire it.

One way to create a strong desire for something is by empathy. How does empathy work?
Say, your goal is to create wealth, but in your heart of hearts, you don't desire it. OK. That's fine. Imagine that there is a person in this world who has a burning desire for wealth. There should be such a person, right?
Then deeply empathize and write down his thoughts in his brain. Write down why he desperately desires wealth and what are his thoughts associated with wealth. Write down this paragraph, as long as possible. This is using empathy to borrow another person's mind. After writing down the paragraph, you will immediately desire wealth, and that's in your heart of hearts, you even don't know why you have that desire. But that's OK, we just need that desire, we don't care why you  have that desire. Don't believe this method? Give it a try and you will see that it works.

Another method is imagination and visualization. Image that you already have what in your goal, imagine the inviting scenario  with it or her, or him, you can also write down that scenario. How do you feel in that scenario, what do you do, what do you say, what do you look at, etc. This method also increases your desire. You may even crave it after this practice.
