You may not know it, but you’ll actually learn some life lessons when you quit smoking.
Life Lesson #1: It is your responsibility to control your mood. 
Before going to work you had a heated argument with your wife because of the missing car key, or while at work you suddenly snap and shouted on the poor maintenance crew simply because he is in your way to the elevator. Nicotine withdrawal causes extreme discomfort which affects your mood. You don’t expect people to always understand and adjust to your situation. You have to be responsible for your mood and learn to control it before it goes out of control and affect other people. And sometimes, the anger you feel is from somewhere else and not from nicotine. You have to deal with it or seek help.
Life Lesson #2: Everything is temporary.
Just like the heartache you felt when your girlfriend left you, or when you failed in your math class, the headaches, sleepless nights, anxiety, and depression caused by nicotine withdrawal will soon go away. It may seem like a lifetime but soon it will be over, and you will start feeling better.
Life Lesson #3: When confronted by difficulties we often look for reasons to withdraw.
Quitting smoking is very hard. It takes a lot of effort to give up a habit and deal with the withdrawal symptoms. And often, these withdrawal symptoms are simply very overwhelming that it deters your determination to quit smoking and go back to the old habit. We often look for excuses, and these excuses are sometimes enough to abandon all our efforts. But if you can learn to overcome this natural tendency, you can better deal with the whole quitting process.
Life Lesson #4: Your body sometimes lies to you.
The anxiety, hunger pangs, achy muscles, panic, and shaky hands, which you feel hours after your last cigarette, are only some of the tricks your brain plays. It may be indicative of a long existing condition, but it is driven by nicotine withdrawal. Nicotine messes with your brain, and it will continue to do so until you totally flush it out of your system, and your body has totally recovered.
Life Lesson #5: You don’t expect everyone to know what you’re going through.
Quitting smoking may be very hard. The withdrawal symptoms are too overwhelming, but you don’t expect your boss, or your neighbor, or the hotdog vendor to know it. This is the reason why you don’t drag people to your misery. Try to control your mood or emotions. But this doesn’t mean, however, that you can’t ask someone for help. In fact, smokers who have friends or family who are supportive are most likely to succeed. You can also look for a support group to help you quit and manage the withdrawal symptoms. The point is you don’t expect people to know what you’re going through (the sleepless nights, headaches, anxiety, etc.), this means nothing to them – so you have to be responsible for your actions.
