As I got older as a smoker, I started to grow very self-conscious of how I smelled when around crowds that were mostly non-smokers (especially at work). After quitting, I started feeling more confident in these type of settings and realized that it was one of many smaller things that made me feel good about everyday life.
Like you just posted, Molly, not having to go out and smoke in crappy weather is also a nice plus.
The further you get in your quit, you will discover many positives, some big and some small, about not being a smoker. It is a positive journey.
