Love in Our Lives

What is love? Well, love is an abstract word which can represent the whole world or just...nothing. Love has an infinity of infinite meanings and indeed it plays a major role in our lives. We all love. We love our family, our friends, our...lovers. We love a dog, a hobby, an activity, a thing, a gesture. All we're doing is loving the whole world that surrounds us.
Why do we love? Because, that's the nature of people. We are born to love. Without love, we are nothing. Love leads us to wonderful things, to different emotions. Some of them are good, some are bad. What types of emotions? Well, jealousy, anger, violence.. or kindness, compassion, change.
When do we realize that we love? When we feel that a person is the only thing we can't live without, well, that's love, guys. We can't avoid it and it definitely doesn't avoid us and we must deal with that fact.
So, love is a necessity in our lives, in all humans' lives. That's it!

Great job...I only had one correction that was more about readability than grammar.

I don't think that love leads to jealousy, anger, or violence. I think possession and obsession, which some people mistake for love, lead to those ends. In my opinion, love isn't selfish.
