How can I quit smoking, drinking and gambling? I want to be a good person.

This requires perseverance and persistence. 1, you should know the harm of smoking and gambling, and remember the harm it does to you. For example, smoking makes your physical fitness decline, your resistance becomes worse, and smoking tends to cause bad breath, which are all women hate. 2. Do it well every day and wake up every day to think about what you did wrong. Don't think about quitting smoking for a long time, just think about quitting smoking for one day, and then tell yourself to quit smoking, drinking and gambling every day.
