Welfare of my society depends on my well being. It is definitely correct. The more you'll be liable and attentive for your society the more will society enhance. Welfare not only means keeping your society clean and green and more. The word welfare emphasises more on the people. That means, your nature decides your position in the society. You should be helpful to those who are in need either children, people of your age or elders. You should give your 100% in everything whether it is regarding the facilities of the society, enrichment or advancement in technology or anything etc. So your contribution means a lot as contribution not only means contributing money it means you are available at the time of need or not.
Hope this helps:)
