Edward falls into his old habits of smoking and drinking when he feels stress at the workplace. He makes progress at work when things are quiet, but when things are too busy, he falls back and slows down.
It is not something he does on purpose but he is aware of it. When times are really busy, he falls in love with his smart phone and escapes into a fantasy world of games and social media.
But now he is in a brand new job at his company. It is much quieter and steady. It looks like things are falling into place for him at last.
