I can just give broad outlines with only that much information. I am assuming that this is an assignment?The first thing you need to do is decide if you agree with the statement that the welfare of your society depends on your well-being. To determine that, you need to define your terms (what is the "welfare of society" and how will we know when it's achieved? What do I mean by well-being? Health? Happiness? Survival? Religious beliefs?) Without defining your terms, any statement arguing for or against that is meaningless, because it's far too general.Once you know what exactly you consider the meaning to be, you then decide if, going by that definition, the statement is true.For example, "welfare of society" might mean its economic standards and its reliance on a shared set of values. (You need to decide what you think is important; these are just two common considerations.) Your own well-being you define as being physically healthy and mentally alert and well-educated; ie constantly learning.So then you'd ask, "do I have to be healthy and well-educated for the society's economic status and/or its ability to have values in common?"The answer to that is your essay. Remember, you can answer yes, no, or it depends quite reasonably; you just have to back up your argument with evidence. (This pretty much represents the classic question of community vs. the individual, so there will be lots to research if you need it.)Good luck! As always, if you have any follow-up questions, feel free to ask them in comments.

what is meant by "society" ?
Society is a long standing group of people sharing cultural aspects such as language , dress , norms of behaviour, artistic forms and thoughts.
what is meant by the word "welfare"?
well, welfare means health , safety , happiness , and prosperity. these are what we all want to have in our life.we want the best for our society .we want to make it a place having all these qualities.
How welfare of my society depends on my well being?
people living in the society always thinks that if the society changes then the other people living in it would also change.This is a very wrong thought.a class can never be called a good one until and unless all the students in it studies and behaves well.The same applies for our society and the people living in it.unless the people start to live a life full of happiness , love , safety and prosperity , the society can never progress.

I need to change my self first . I have to  be a good person and be loving , caring and helpful to others.I cannot be rude to others and expect others to be kind to me.This is not possible.we all know that , " as we sow so we reap".If I start the change just as sowing a seed then automatically others would follow me and gradually the whole society would change and become the best one just as a big and strong tree.when other societies would see this change in my society then they would also soon try to improve themselves which in turn would improve the whole society.This is how the welfare of my country depends on my well being.
