I believe you are talking about the Sergei in the “What, of This
Goldfish, Would You Wish?” If that's so, then the theme about happiness presented here is that people hold onto different things for their happiness. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
Answer:
Depending on how you act or interact with people can have a major impact on how others see you and can even change the way you see yourself such as if you were to be hostile when interacting with others you would be defined as a hostile person or if you where kind then you would be defined as kind and outgoing.

Hope you found this helpful :D
(Note: In my opinion I believe nothing defines who you are. You are who you choose to be and you should just be you.)
Here are my suggestions on what you should edit:
Should cigarettes be illegal? Smoking can cause lung cancer, strokes, and many other diseases. Diseases caused from smoking are one of the most preventable in the US. In the States, more than 480,000 deaths occur a year due to smoking related illnesses. Smoking should be made illegal to protect our health.
I changed it up because you need more variety in your diction (wording), and also the phrasing could be slightly improved. When you wrote "In the US, more than 480,000 deaths occur a year due to cigarettes" the phrasing didn't make much sense. You don't die from a cigarette. You die from diseases that are caused from regular smoking.
Hope this helped!
