The success of a residential interior design project depends primarily upon how well is achieved the ultimate goal.
What is the ultimate goal for this interior design project to achieve?
Why is it being undertaken? Who will use it? For what activities will it be used? What is the optimum ambiance?
When such is finalized, the process of achieving it is like taking a trip to a desired place.
When flying, you go from where you are to where you want to go in one action.
When driving, you travel in stages of action to get where you want to go.
The same concept can be applied to manifesting a residential interior design project.
The entire project can be completed at one time, or it can be completed in stages.
In both manifestations, keep the direction needle always pointed to the ultimate interior design goal without any distractions, side trips, changes, waylays, et cetera which may detract from reaching this set desired ultimate goal.
Always, keep your eyes, and focus, on the ultimate interior design goal.
Thusly, you can arrive at said place.
Food for thought.
