We might even deliberately do an action inefficiently, for example opposing muscles against each other, in order to enhance sensation. (i remember deciding to do this as a teenager. oops)
If an action causes no or little sensation, we would not necessarily realize we were doing it. That we can control our actions might be something we do not know instinctively, but must learn.
More generally, supposing we have some goal we are oriented towards and then encounter an obstacle. We could orient to the obstacle, pushing directly into it to overcome it, but the tendency then becomes to start to orient one's life wholly to the assault of these obstacles. Better to stay oriented toward the goal, slipping or bouncing around the obstacle, or attacking it in a way diagonal to the obstacle's internal organization. If we do not oppose something directly we apply not only force but torque to it. Even if its structure would survive a full frontal assault, it may shear and shatter when attacked at an angle.
The consequences of this may be complex beyond prior analysis, we may be unable to fully plot our path to the goal ahead of time. Eh. Make some progress, then see where you are at. Ignore irrelevancies. Feel it out. Don't assume the problem is hard or that great effort is necessarily required.
The enemy's gate is down.
I wonder, is this what people mean when they say they have put their life in God's hands?
