If you are inclined to assist others in any situation, you are a helpful person. Your actions can also be called helpful, like your helpful habit of doing the dishes every night.
If you want to be helpful, you find ways to make things easier for others, like holding the door for them. Things can also be helpful — maps, cell phones, dictionaries, and holders for wet umbrellas. Taking good notes and setting your alarm to go off early are helpful tips for days when you have big tests. A discussion is helpful if it teaches you something new or gives you ideas for doing something better.
