Yogi: I’m always fearful of overlooking something especially when the mind is not alert. That creates fear and doubt about what if I miss something. Because it is constantly present, my mind is always effortful not to be in that state. It is more obvious when I meditate, but it also happens in daily life.
Sayadaw: When you’re afraid, fear destabilizes the mind and you’re more likely to make mistakes when the mind is not stable.
So, it is not necessary to be afraid and it doesn’t help your mission not to miss out on something.
Whenever you notice fear, recognize there is fear and be happy about it. And if you recognize this fear very often, over and over again, eventually the mind will figure out something about the fear, about whether it is helpful or necessary or not for you.
