I got to thinking about this question in some depth and reflected on the words I wrote in my June 1st update about my childhood and the long days of summer. Then I came to the conclusion that I have enjoyed "finding things" since I was quite small. Not just sea glass. And it seems to be one of those things in life for which which I evidently have a "natural talent" of sorts.
Although my interest in sea glass dates to my childhood, there were many other things I spent time "finding," when I was young-- and I still do.
One of my other hobbies-- which eventually turned into my "day job"-- is collecting stamps. Again... especially if you're trying to make money at it... this is a pastime that revolves around finding something. In the case of stamps, finding something other people may have overlooked.
I'm also really good at finding treasures at flea markets, finding lost keys, and even finding places in cities when other people are lost.
Unlike many sea glass enthusiasts-- who collect sea glass in order to use it in some way, or display it in some fashion-- I really don't inherently possess much talent in the realm of "creativity." Sure, I could probably "make something" with the sea glass I find, but odds are I'd need someone else's design to look at and "copy," in order to produce anything worthwhile. Whereas I really enjoy the aesthetics of creativity, I have approximately zero ability to visualize something original in my head, "out of thin air."
And so, I find sea glass for the simple joy of finding.
Which led me to the answer to something else people often ask me: "I just don't understand how you can not KEEP all your beautiful sea glass!?!?!" Truthfully? Once I've found it, held it and enjoyed that process-- along with the zen-like "meditation" that a 6-hour walk along the beach represents for me-- I have very little attachment to "owning" the glass. With very few exceptions, one piece of cobalt blue sea glass is pretty much like any other.
In fact, it actually fills me with more happiness to know that someone artistic is finding joy in creating something beautiful with my glass, rather than just having it sit in glass jars (pretty, I do admit!) collecting dust on my windowsill.
That said, I do have a fairly large personal collection of seaglass, assembled over the past 40+ years. And I still do add to that collection. But, on average, I probably "save" two pieces for every hundred I find-- which means there is quite a lot I end up selling on eBay and Etsy.
