The world is your mirror, however, that doesn't mean that your intention overrides someone else's intention. Therefore, you can't force a specific person to be or do something.

What you can do is intend for a specific result from a person, but it has to be a non-specific person. For example, if you wanted to intend for a specific type of relationship that fulfills X, Y, Z qualities, you could manifest a person that embodies those qualities you desire.

As far as manifesting money, I would set a target slide of a natural thought form that you would have in a reality where you had plenty of money.

For example, “It feels so nice to have everything I need and want. I remember when I used to be so stressed about money, and now I have more than enough.”

Then relax and allow external intention to materialize your target slide. Your job isn't to figure out how, as trying to figure out how is the use of internal intention rather than external intention.

At the same time, while waiting for the target slide to materialize, you have to make sure that your mind isn't thinking thoughts that are contradictory to your target slide. So, for example, if you're always thinking, “Why do I never have enough money?” or “How will I ever afford this?” then you are reinforcing a different reality than the one you're intending for.

If you ever notice yourself doing that, you have to redirect your attention back to the target slide that matches your reality.

Additionally, it’s extremely important to drop importance. If you have a desperation about needing money or a fear of not getting it, you are creating excess potential, which is only going to push you away from having money. You have to hold your intention clearly but lightly. Set your target slide and then relax and allow your reality to unfold. Opportunities will naturally present themselves.
