Visualization Realization

For months now, friends have been talking about visualization techniques. How thoughts become things. Creating vision boards. Dropping into theta wave states. Manifesting reality by imagining it.
I just didn’t get it. I can close my eyes, bring myself into a calm, deep meditation and imagine walk down an imagined forested path to reach my heart’s desire, only there is never anything at the end of the path. Looking through a magazine for images of my goals and wishes only frustrates me.
The trouble is that I don’t have many goals or desires. There are things I want to achieve, but they are either already happening or just not that important. I’m not particularly interested in riches; I have a good marriage; I am happy most of the time; my health is acceptable. Sure, I could wish to amp up any or all of those but I feel that the basics are covered and anything else that comes my way is a bonus which I do not particularly seek.
And here is the realization: even though I seem to fail at my own visualizations, I can imagine the way to someone else’s concrete goal. If someone puts me on a project, I can visualise like crazy. A design for the party dress pops into my head and then I start to figure out how to build it, imagining exactly what sorts of fabric to use and how to trim it. Or I see how to schedule six simultaneous video projects, reuse resources to cut production time and keep it all within budget. Birthday cake? I will know the appropriate flavour, filling and frosting in a blink and can give you a schedule of when it will be made so it is fresh and ready for the big day.
No doubt there is some deep significance in this. Am I not self-motivated? Maybe I lack creative drive or innovation. I don’t know, but if you give me something to do, I can see clearly how to do it.
