Sometimes undoing is as important and difficult as doing and takes as much time. Sometimes people who seem to lead average lives are actually working to transform themselves from within. Sometimes learning what you are not is as important as learning what you are.
Self development may be subtle and within, like an underground current. Don’t give yourself hard time that your actions are not external, do not bear visible fruit. Do not think you should instead focus on something more ‘tangible’. You are doing important and difficult work and it will manifest itself one day, like water against rock. Keep going.
