I feel like the way to think about troubleshooting is to think about it as an umbrella encompassing reliability and quality engineering in software. If you can find ways of showing how reliability and quality of a software can be broken and how it can be improved (simultaneously), then you have a career to make. Don't wait for stuff to break and react. Be proactive and find ways to demonstrate how it can break and how to fix it.
