1. Don't try to replace the smoking habit, remove it first. Find what is triggering it. * It could be a person, i.e you smoke with your SO or with your best friends. * It could be a situation/place, i.e you smoke when you sit on certain couch, chair or laying in bed at certain hour. * It could be an action, i.e before/after I play video games I light it up. Trying to avoid those triggers. 2. Show up everyday. When you get back your time, focus and ambition. Do something productive EVERY-SINGLE-DAY. Read CS/Programming Books, watch quality online courses, develop random side-projects (a blackjack game, an adventure text-based game, youtube clone). I was on a similar spot; but with video games and gambling. After 4 years of showing up everyday, weekends, holidays you will become... pretty pretty competent. Even if you are not brilliant, as myself. Goodluck
