Hi! Thank you so much @skycae! Your delegation sure will be handy to promote live sustainably posts such as yours and many others :) 

About quit smoking, that's indeed a big deal because people have deep pleasure doing it so intrinsic motivation kicks in no matter what. Just like your friend did, focusing on other internal regulation mechanisms will help get around that (still external causes are strong, specially the money part - some people pay for cigars as much as for the rent!). But the pleasure of smoking stays forever, that's why some people after 20 years of non-smoking often say "sometimes I still want to".

Thank you again for your comment and your delegation! And also for submitting it to curie and steemiteducation :)
