Does anyone deliberately limit how often they look at their portfolio?

I follow a fairly standard index-based approach, so strategy isn’t really my issue. What I’ve noticed is that most of my stress comes from *how often* I check — not from allocation, fees, or performance. Lately I’ve been experimenting with a simple rule: only review once per month, using a short worksheet to note what changed, how I reacted, and then close it until next month. Curious: * Do others here deliberately restrict portfolio checking? * Do you use any kind of rules, logs, or review rituals to avoid overreacting? Or do you think this kind of structure is unnecessary if the strategy is sound?
