The habit of helping others

One of my Grade 9 students, still learning English, wrote this in an essay:

Helping others are also very easy. You can volunteer only one minute to others. For example, pick up rubbish, five seconds. Wait in the elevator while people are coming, five seconds. You can only use a minute to help others. Then, you will have a habit, helping others. No one forcing to help others, you get habit, that is the greatest habit in the world.

Couldn’t say it better myself.
