One advantage of having people you can depend on is what we call "leverage." With their help, you can have more time to do the things you really want. And whenever you need anything, they might know someone (or someone they know might know someone else) who can solve your dilemma.

So it pays to be nice to others. Show your kindness and generosity to others, and they will return the favor. The Law of Reciprocity works like a charm. People will feel compelled to return any act of goodwill you've shown them.

However, don't go about being nice to others while expecting something in return. Do acts of kindness unconditionally. Don't demand from others, saying something like, "I've done so many favors for you, now I want you to return the favor." No, that's not the way.

Just do good things. Even if people don't remember or appreciate what you've done, the Universe will certainly give you the reward that you deserve. Yes, the Law of Karma is working at all times.

And one very important thing I want to point out ..

We acquire the behavior or attitude of people we spend the most time with.

So it's a good idea to stick with positive friends who will uplift you and help you become a better person, instead of being with people who are pessimistic about life. That's not to say totally avoiding negative people. Just learn how to filter. Absorb ideas/suggestions that will help improve your life and develop your personality, and leave out the so called "garbage stuffs" that will do you no good.
