let go
If I let go of anything, I put myself into the position to freely choose whether I want to continue pursuing it, doing it, keeping it. It is important for me not to just get attached to the opposite, but to let go of the question itself whether I want to or have to or need to pursue, do, keep it.
I let go of the results of my deeds. I do not attach to the result I expect from something I do - which obviously makes the expectation itself redundant.
