I want to quit smoking, can you give me some tips ?
Honestly you just learn how to avoid blaming others ("why are you so annoying") and apologize quickly. For me it was really learning how to deal, calming down away from the stress, and coming back to the environment to handle it in a rational way. If you let the people around you know early that you're trying to quit, they can help support you. But when it comes down to it, sometimes all you need to do is count to ten in your head and let it be.
Besides that, sometimes you need a couple running starts at quitting. That's ok, forgive yourself and learn from what caused you to break.
