Realizing that changing your environment so that it encourages the right outcome is orders of magnitude beyond being a basic, mediocre grown-up who relies on discipline and will power, which is easily depleted, to overcome an onfavorable environment. No one should settle for relying on discipline and will power. That's a moralizing exercise in futility. I've had this argument with my stepfather until he became abusive. The result: I stopped talking with him. It has been one year. Reserve your discipline for differential association and for improving your environment.
