You make it sound almost easy, a sign of a master.
Other good signs are not claiming that title or professing to be one.. ever. Kinda like telling your motorcycle peers "oh yeah, it'll start" or that you're an excellent/expert rider. What often happens in short order?
When I was apprenticing, I used to refer to my Masters by the title in a gesture of tribute and honest respect. Every time, they told me I was a fool, wrong and "didn't understand" what I was saying. Decades later, they still say the same thing even though each one is even more of a Master than ever. I understand better now, because although I know more than ever before I also know more about what I don't know. So I do and don't do what they did. The word Master is used, but not by the individual describing self. That's one of the most important lessons they taught me.
That's just the protocol in our craft. Other trades like plumber or electrician or chef may employ a finite test or process to certify an individual as a Master. Some trades more like mine, such as a custom woodworker or stone carver (doing limestone architectural work) have guilds that will allow a craftsman to advertise as a Master after completing a complex job or series of jobs that is equivalent to the work an older Master in that field would produce. Our work isn't like that. It doesn't matter what your specialty is. If you're good enough, your peers in the granite industry will call you a Master. But if you claim the title for yourself, disaster is licking its lips and the rest of "us" will know that you are not.
No matter, thank you for the compliment. Some jobs, like this capital, remain hard to comprehend after the fact. I/we know I did it, but it's more like I was just there getting to do it. I'm just happy when I get to be in in the right place at the right time.
