There are many potentially good community service ideas. There are many humans and animals that need help. There are many causes to contribute time, money, and energy to.
Community service is worthwhile to perform. Helping others can bring on good feelings. Hopefully, poverty can be eliminated on Earth. One can volunteer to teach or tutor others. One can pick up trash off the streets. One could remove graffiti. One could volunteer time at a soup kitchen, food pantry, or another non-profit organization. One can volunteer at a church. The possibilities are just about endless.
If one has lots of wealth, one can simply donate money to charities. So, in one sense, becoming wealthy is a way to be able to help charities, potentially, at least. If everyone performed more community service, this Earth might be a better place to live. If one is a medical professional, it seems there are likely ways that one can donate their time and expertise to help others.
There is probably no best one type or way to perform community service. Ideally, community service should be done voluntarily, it seems. Perhaps one should wait until they can support their own self before going out to try and help others. One should perhaps look around their own local community to see what seems the most needed, and then try to devote time and energy to volunteer in that area or sector.
Every community is different, and every community will have its own specific areas that might need or could benefit the most from volunteer helpers. Helping others can be quite fulfilling and volunteering can serve to help one feel good. It is perhaps alright to be selfish in this respect. 🙂
Not everyone is able to volunteer. Some individuals are disabled and would have a difficult time volunteering even if they wanted to. That does not mean that there is no way for them to volunteer, they just might have to look a little bit harder to find something that is a good fit, or else find a place that can accommodate their disability.
Hopefully, more individuals will provide voluntary community service to others on this Earth. Perhaps, if that happens, everyone on this Earth can live a little more prosperously.
