It’s not really about strength IMO. It’s about mindset, it’s about community, it’s about knowledge. Allen Carr’s book helped me greatly with the right mindset. Knowledge I gained by reading and watching articles and videos abpout smoking and how to quit. Community you can find here in this thread:
Or there’s more specialized forums, totally dedicated to quitting smoking, on the web too. You can do this! In the end it’s the smoking that exhausts and kills us!
