Anxiety doesn’t generally come from making decisions, but rather from the time spent deliberating on whether to make a decision. 

At a certain point there’s enough information gathered, and a choice should be made. That choice isn’t always Option A vs Option B, but could include Option C all the way to Option Z. 

If you’re struggling with a decision, use the best data you have now and decide (even if that means intentionally deciding not to act, just be direct about it). You’ll be wrong sometimes, but the anxiety of it will hopefully lessen.
