Hello, there! I just want to share with you my story.
A friend of mine introduced me to LOA. She manifested so many things: from wealth, relationships, family concerns, etc. I became interested to I googled it up. Turns out, there are so many ways to manifest your goals into reality.
For me, I listen to subliminals every night, before I sleep. While listening, I always visualize him sending me a message. One night, I tried visualizing him chatting me on facebook. I didn't visualize the content of his message, I just imagined him exchanging messages with me. What's funny and interesting is that, after one week, he waved at me on messenger. But when I asked him why, he just said, "nothing". Then I realized, maybe because I never visualized the content of his message that's why he won't tell me why he waved at me! LOL!
So next time, I recommend you to visualize your desires CLEARLY and COMPLETELY!
Yes, there is a balance you can strike between being too specific (and having doubts whether it will manifest) and being too vague (and not really manifesting much at all).
So for instance, if you want a special someone, it can be hard not to visualise them without a face (so as not to be too specific). What you could do is visualise lots of different people with lots of different faces and that will give the Universe some creative leeway.
Another example, if you desire a lot of money, don't visualise where it comes from, what you could do is visualise yourself paying it into the bank, or looking at a banking app and seeing a healthy balance, or looking at a credit on a bank statement for a large amount, but not saying where exactly it has come from.
For or manifesting your dream home, visualise what it looks like inside, and in the grounds, but don't say where exactly it is, or how it comes to you. Those are the look-outs of the Universe, and it knows what is right for you.
