How do you spot a task worth automating?
For a few days, write down the tasks you repeat: sorting messages, moving data, making reports, scheduling, and following up. You are looking for a small, familiar process with a clear beginning and end.
Which task should you pick first?
The best first project is usually not the most impressive. Pick a task with reliable inputs, a useful output, and a result you can easily check. A weekly summary is a better starting point than an unsupervised business decision.
What should you write down before building?
Write down the trigger, the information you need, each step you take, and where the result should go. If a step depends on your judgment, make that decision visible in the workflow.
How do you know it works?
Test with examples you already understand. Compare the output to your own work, note the failures, and only expand after the small version is useful.
