Thanks for thinking of me, I’m glad you found my thoughts helpful enough to ask for more. 
I’ve heard numerous people talk about synchronicities and manifestations happening so obviously they are like magic, but I can’t think of any examples where it’s happened to me. Just yesterday I was attending a virtual conference and one of the speakers was talking about synchronicities jumping right into his face, and gave the example of a book falling off a shelf without any obvious cause, and opening to a page that had just the insight he needed at that moment. I’ve had things occur that were low probability, but still within the realm of possibility, due to precursor events or situations that had been set up.
So, with that being said, my advice is still to work on setting things up to be possible, and then visualize/intend the desired outcome. I personally have a hard time imagining that checks will just magically appear in your mailbox if you intend to be wealthy, although I begrudgingly admit that I do know people for which that has happened in some form. So, probably a limiting belief on my part.
For money stuff, there’s 2 ways to have more money… spend less and earn/generate more. Ideally, you’d do both, although there’s a lower limit on what expenses you can cut, and no actual upper limit on what you can generate with the right resources and situation.
Set goals that are doable, take whatever action steps are needed to help them become possible, and then visualize the desired outcome. I wouldn’t advise just setting an intention and letting the universe figure it out, I firmly believe you (everyone, not specifically just you of course lol) need to do your part.
Making money, for example… I don’t think you can manifest a successful marketing campaign without doing any work, but I definitely believe you can manifest people being more receptive to one that you actually build and execute on.
Saving money: Set aside a certain percentage of your income for savings - this is personal finance 101, yes. but hear me out. Save whatever percentage you’d otherwise have spent on luxuries… dining out, nonessential clothing purchases, etc, and set the intention that you will experience those things anyways. Perhaps you get invited to a social event at a restaurant and someone else pays as a treat, or maybe you discover your favorite clothing shop has a huge sale and you can get a steal of a deal on something you would have bought anyways.
(Examples clarification: I’m hungry at the moment so thinking about food, and I’m also looking at sweaters on LL Bean hence the clothes shopping example lol)
There’s the old expression, you can lead a horse to water but you can’t make it drink… you can intend for the horse to drink all you want, but if you’re in the middle of the desert not much will happen. In this example, of course, the horse is whatever you want to happen. Do whatever it takes to get the horse to the water, and then let the intentions take over.
Apologies for the rambling post, I woke up with a migraine and have been propping myself up with strong coffee and Advil to deal with it. Brain isn’t at 100% today.
