Do not relent! Staying sober is like walking up a mountain path. just climb what is right in front of you for that day. Do NOT think about what lies ahead, as you are not the person you are going to be when you encounter tomorrow. Each day builds on the last. And each day the view is wider, and the possibilities you see for your life expand. And your emotional muscle strengthens.
You will not want to slide back down that mountain.
Trust the climbers ahead of you. They will tell you how much stronger they feel and how much a sober life continues to surpass their hopes and expectations.
And don't forget to look around wherever you are, be grateful for it, and enjoy the view!
