I'm an avid collector of fountain pens. Collectors usually have a "Grail Pen," a pen that is highly desirable yet ultimately unobtainable because of cost, scarcity, or other factors. In general terms, a "Grail" is the highest thing one could aspire to obtain or accomplish in any hobby or goal. This item, ability, or status might seem ridiculous to other people, but for enthusiasts, it's incredibly valuable.
So, Hubski, virtually everyone here has an obscure hobby/goal. What's your grail? How do you know that you've become the best you can possibly be?

(Also, check out Namiki Pens to see some seriously beautiful craftsmanship. I hope to own one some day, if I'm ever rich enough!)
