What made it even better was talking about how far we’ve come as an ecosystem:

🧰 From Oculus Integration to the latest Meta SDKs
⚡ Faster iteration + smarter tooling
🚀 New features like the Quest Build Profile & Meta Quest Runtime Optimizer that makes performance tuning so much easier.

I shared how I’ve kept creating videos even as life, family, work, and now my role as a Meta Developer Advocate continued to grow.

The physical items don’t bother me as much since insurance will likely cover them, but losing the hard drive with all the content for my next video honestly makes me really sad.

The video took 3 weeks to make, and I only had a few small tweaks left before releasing it this week.

It also gets easier when you look back and see your progress. Even if the progress is small, it motivates you to do more and helps you get into the zone.

For me, it has been very challenging to keep making videos. Work and life get busy, but instead of giving up and saying, “I don’t have time,” I break the video into smaller, manageable tasks.
