The best first automation touches one app
When you're new to building workflows, pick a first project that stays inside a single app or connects just two apps at most. Save the projects that hop across five different tools for later, once you've built confidence with something simpler.
A workflow that only touches one or two apps is much easier to picture in your head, much easier to test, and much easier to fix when something behaves oddly. I still start every new build this way, even now. Projects that stretch across many tools multiply the number of things that can go wrong and make it harder to tell which app caused the problem. Starting small also teaches you how your tools actually behave before you ask them to work together in a longer chain.
Once a simple workflow is running smoothly, adding a third app to it feels like a small step instead of a giant leap.
Try this today: pick a task that only needs one or two apps and build that before attempting anything that spans more tools.
