The world of reality has its limits the world of imagination is boundless.

Constraints exist wherever anything is actually built, and no amount of vision removes them. What is unlimited is the space of what could be considered, which is exactly why it is worth spending time there before you begin negotiating with the possible. Most people compress their options long before reality requires it.

When you are stuck, separate the two stages. Spend twenty minutes with no constraints at all, then bring the results back and see which survive contact. The good answer is rarely the one you would have reached by staying sensible throughout.
