Visualization is something that lends itself to practice. I remember discussing this with one of my art teachers years ago as they said that they have a complete artist's studio in their head in which they will create things mentally before, or in addition to, creating artwork in a real studio. Their analogy on how vivid the visualization is that it is similar to hearing your thoughts versus hearing yourself say something. Whether it is worth the time to go through the effort of visualizing something depends a lot on the task at hand, the cost of making mistakes working it out for real versus working it out mentally beforehand. It's not like virtual reality but it does save me a lot of time in figuring out how to construct and put things together, or identify promising design paths.
