Well I think one of the key things to knowing you truly desire (notice I say desire not “want” which means “to lack”) is by looking at what brings you joy. Literally that can be a great starting point, asking yourself what brings you joy and then noticing where your awareness takes you. A large part of the LOA is about feeling good and its for good reason that’s suggested. You see when you are feeling good, have you noticed the world seems to run smoothly and everything is a joy.
Now re the two manifestations – great start too. Now having doubts isn’t a bad thing, and it can help you get really clear on what you desire to create. And there may be something better for sure that you will discover in going for these targets. Likewise it may be that these targets appear in your life differently than you currently imagine too.
Now one thing I like to do often is with things I am desiring to create in meditation is asking my body to show me what it feels like to have that thing already. So for example, prior to my relationship which has been going very happy now for 5 years, and we are getting married in August, one of the thing I asked my body daily to show me was what it would be like to be in a long term happy loving relationship. I then became aware of feelings and sensations that I would have when that showed up, but I started being that vibration in the present moment and I truly believe that’s a large part of why I attracted the relationship I did. Also when I bought my third property, I again asked my body to show me what it felt like to live owning three properties and I noticed that the way I moved changed, I seemed to flow smoother and freer. These explorations really helped me to create things faster and I share them with you simply for you to try. They may or may not work for you but at least it’s a starting point.
The reason you feel unsatisfied is because you are currently living as if you are devoid of the two things you want to manifest. If you went about your life as if you were satisfied, you would easily manifest those two things. It's important to assume the person you want to be to become that person or live in your desired situation.
