Pick your fights carefully

I've not been able to do many trades recently, as it's been really busy back home. One thing I have noticed, which should help me improve my strike rate, is that once I get started, I keep doing trade after trade in the same market. Some work others don't. Yesterday, I tried to be more stand off-ish and to pick my trades more carefully. It made a difference. I walked away with no losses. So my thought for the day is "pick your fights", don't just dive in. Pretty obvious, I guess, but I was still doing it.
