Mental help: In this world full of tensions and competition, when people fail to get what they want, they get depressed and try to harm themselves by one or other things such as attempting suicide. One can help them by providing moral support and motivating them.
Physical help: There are many situations when someone has to carry something from one place to another, but due to illness or other problems they cannot carry, one can help them by carrying their luggage. Blood donation or donating body parts of a person who died is also one form of help.
Financial help: We find many people who need food and money sometimes for one thing, such as paying the debt. We can provide them with money to help them.
Along with all these helps you make someone laugh in odd conditions; Mentoring, teaching someone good habits, and providing something to someone that makes them happy is also helping someone.
