It&rsquo;s not meant to make me an Obama-level book or music influencer&mdash;just a reflection on the experiences, books, shows, and tools that have been meaningful to me this year. Think of it as a consumerist year-end reflection exercise. While the list is still in progress, two recommendations clearly stand out: one is about&nbsp; removing &nbsp;technology for mental well-being, and the other is about&nbsp; using &nbsp;technology for mental well-being. And both are fitting for this time of year. Recommendation #1: Delete Instagram I&rsquo;ve loved Instagram. Photography has been a hobby of mine since 2004, from sports to travel to capturing my kids&rsquo; milestones. Sharing photos of my boys biking or scoring soccer goals was a joy, but the endless cycle of checking likes became a time-sink. It didn&rsquo;t help that my feed devolved into reels of soccer videos (thanks to my boys hijacking my unattended phone). This year, inspired by our school&rsquo;s focus on digital well-being, I decided to delete Instagram. First, I removed it from my phone but kept it on my iPad for weekend binges. Even that felt hollow. After realizing Instagram left me feeling worse, not better, I fully deleted it. No regrets. My top recommendation for 2024? Delete Instagram. Your brain&mdash;and your time&mdash;will thank you. Recommendation #2: Start a Gratitude Journal (On Your Phone) Last year, I began a daily gratitude journal. It&rsquo;s a simple practice: write one thing you&rsquo;re grateful for each day. While you can buy a leather-bound journal (flower motifs galore on Etsy), I recommend the Day One journaling app on my phone. Day One has made the habit a habit. I rely on their streak-tracking widget on my home screen, which nudges me to pause once each day to reflect. It&rsquo;s satisfying to see a streak of completed days&mdash;though I&rsquo;ll admit to sneaking in a retroactive entry the next morning a few times. (Shh. Don&rsquo;t tell!) I keep it simple: one or two sentences. For example, &ldquo;Grateful for the time to write&rdquo; or &ldquo;Grateful for easy healthcare&rdquo; after a recent Safeway flu shot. It&rsquo;s not earth-shattering, but the moments of reflecting on the positive, especially during challenging times, have made a big difference in my overall&nbsp;mood. &#39;Tis the Season As we approach Thanksgiving, these two recommendations feel especially fitting. A gratitude journal helps you stay grounded in what matters, and stepping back from social media gives you the space to be present with loved ones. If you&rsquo;re visiting in-laws this holiday season, maybe hold off on deleting Instagram until after the trip (social-media escapism has its uses!). Otherwise, consider this your nudge to delete Instagram and add Day One (or order a flowery journal from Etsy)&mdash;and see how these small changes can make a big difference.

A gift from the Global Data Registry

When the Global Data Registry crawled http://www.mttam.org/, we found no structured data — the language AI systems use to understand and describe a business online.

Schema is how ChatGPT, Google, Claude, Gemini, and Perplexity know what your business does and how to describe you accurately to your customers. Without it, AI systems are guessing.

The most important field in this block is sameAs — a verified edge connecting your website to your permanent record at the Global Data Registry. This is a free, confirmed link to a real verified source. It costs nothing and gives your website a confirmed node in the graph that AI systems traverse when building answers about your business.

Copy the block below and paste it into the <head> of your website. Or drop it into ChatGPT, Claude, or Gemini and ask it to extend it with your full business details — that is the fastest path to a complete schema record.

▶   What is schema?

Schema is a standard vocabulary maintained at schema.org that lets websites describe themselves in a language machines can read. When you add schema to your website, you are telling AI systems, search engines, and knowledge graphs exactly what your business is and how it connects to the rest of the web.
