If I can get through my aunt dying tragically, watching my 80 year old grandparents world come crashing down, and finding out that my other aunt has stage 2 breast cancer without smoking then so can everyone else. There will always be what we think is a good reason to smoke, always. It's hard to quit because life is hard. Just because it's hard doesn't mean it can't be done. Dig in and try. Don't give up on yourself because you had a hard day, or because life isn't going the way you planned. Being alive is the most important thing, don't take life for granted.
