We are taught from childhood that excess is inherently negative. Certainly, as a trained artist, I had a certain version of that idea reinforced throughout my studies. But thankfully in that training, there was also the affirmation that part of the purpose of knowing the rules and boundaries thoroughly, and especially the valid reasons for those having been codified as The Way to Do Things, is so that when we choose to break the rules, cross those bounds, and color outside the lines, we will do so intelligently and with purpose as well.
Otherwise there would be no invention at all.
Imagine if those who developed the magnificent decorative beauties of the art and designs prevailing in Art Nouveau work had always held back and refrained from going a bit beyond the norms, never mind whether any of the magnificently ridiculous extremes of the Baroque and Rococo would have bloomed in the darkness. Think, if you dare, of a world where experimentation and thinking outside the proverbial box were forbidden: would any of the useful, meaningful, and beautiful inventions that save lives and enrich them ever have happened?
This idea can be expressed on a much smaller and more modest scale, too. Why not let our joy in excess sometimes shout its existence for others to bask in its reflected glow!
