How do I know if I'm genuinely learning from my past or just overthinking?

Here's the test I use: genuine learning changes behavior or perspective. Overthinking recycles the same loop without landing anywhere new. If you're asking the same question for the hundredth time and arriving at the same answer, you're not learning—you're circling. Real reflection is quieter. It lands as a small shift in how you see something. You learn, and then you're done. The mind moves on naturally because it has what it needs. Overthinking, by contrast, feels urgent and unsettled. It demands more time, more analysis, more certainty. But certainty about the past is impossible; you only ever have incomplete information and your current interpretation of it. So ask yourself: am I trying to extract something useful, or am I trying to achieve certainty that the past was different? If it's the latter, you've already lost the thread. Set a boundary—examine the situation for a day or a week, then redirect your attention to what you can actually influence: today. The past doesn't need you to solve it. It needs you to learn from it and let it inform, not define, your next move.
