Sometimes the right thing to do is easy, but it can be hard at times. In those times, it might be worth revisiting the stoic idea of doing what you can, where you are, with what you have.
If you have evaluated available information, and acted on it, you have done what you can. If that decision turns out to be wrong, you have learnt as much as when it turns out to be right. In many instances, you will not even know whether it was right or wrong, and for whom, and that’s ok.
