Which commitment should I make?
One could simply commit to the awareness of:


  This is not mine. This is not my self. This is not what I am.


Notice that quote is prefaced by the following introduction that addresses the question's focus on action and consequence (i.e., form):


  Rahula, any form whatsoever that is past, future, or present; internal
  or external; blatant or subtle; common or sublime; far or near: every
  form is to be seen as it actually is with right discernment as...


With right discernment comes a relinquishing of self and an openness to other questions and other suttas.

Also, given the expressed concern about consequence, there may be fear and terror here, in which case the Bhaya-bherava Sutta: Fear &amp; Terror Sutta may be a helpful exploration.
