True indeed. We are responsible for ourselves.Nobody comes to save us. We might have wives, friends, a shrink whatever but at the end of all this, we remain there alone with ourselves. If someone should save us from the chains of porn, is actually us. People can only give advice, tell us what they think, what worked for them but at the end of the day we are alone in our head with ourselves and only we can save ourselves.
Are you practising or considering yoga or meditation? They are very good techniques of self-discipline besides fostering both physical and mental health. Might help in diminishing those urges.
