What are your thoughts on complex words we have created as a feeling love, happiness, etc.?

Many create an image in their mind what "happiness" looks like or should look like....This is the ultimate illusion of self. Think of all the influences which help to build and paint this illusion personally. If you don't know what your happiness looks like you have not produced an image to build to. Therefore you don't have a happy illusion and are hopeful it arrives as advertised by the word. Rambling and just want others ramblings :)
