I'm a middle-aged man and I want my first tattoo

I've given a lot of thought to what my tattoo(s) would say. Since they're stuck on me for life, they need to be meaningful.

For sure, I know I want a tattoo that says "timshel" which comes from East of Eden by John Steinbeck. There's a whole beautiful verse in the book about the meaning of timshel, which the author explains translates to "thou mayest" -- or, we can choose our destiny. Caveats: I'm not religious, and I understand that Steinbeck didn't get the translation quite right. But I don't care about that -- it's the verse itself and the meaning behind it that is so powerful to me. I want the "Steinbeck timshel," not the actual Biblical translation.

If there will be a second tattoo in the future, I'm leaning toward "this too shall pass" but I'm not quite as certain on that one.

Since I'm a tattoo virgin, I have all sorts of questions:

• Where's the best place to get a "timshel" tattoo?
• So what do I do, just mock something up in Adobe Illustrator or tell the artist "here's what I want in this font"? Or do they have a bunch of presets?
• How do I find a good tattoo artist?
• At this stage in life, should I rethink this scheme altogether?

EDIT: I want this/these tattoos to serve as reminders for myself, not to show off to other people. Not that I care if other people see them... Not sure if that helps with placement.
