What thing that you hate but you have to face it everyday?

I hate to smoke. Yes, I hate to smoke nowadays and I have tried my level best to quit smoking but everytime I have left cigrattes for some one hour or so , I can find one of my friends , employers or colleagues smoking. It's hard for me to resist to smoking then. I wish I could leave smoking anytime in my life and be a normal guy. I'm thinking of joining any rehab centre to quit smoking.
