Love is... It's kind of... Sort of like a... Hm. Love is important. It is shown that single people are more likely to live shorter than people who are dating or who are married. Love is also a feeling that is needed to live. Everyone feels love, it doesn't matter how tough you are, or much of an asshole you are, everyone has the ability to love and can feel love. It's what brings meaning into the world and it thrives us to be better people. If you have a bad relationship and it's your fault you broke up, then it's a learning experience. If it's the other persons fault, then they have to overcome their problem to better themselves. Love is just the greatest feeling in the world. (Not that I would actually know what that feels like. It's just what I'm assuming.)
I mean love may be a great feeling, but there are people who will never feel love because of many reasons. The first one being they're unattractive and no one wants to date them. Another example would be extreme anxiety, making it difficult to even meet girls. Another huge one would be your personality. I learned the sad truth that if you want a girl, you have to be an asshole. Why? I don't know, I really don't. It's the way the world works I guess. I mean I once asked a girl why they chose the guy who treats her like crap, over me, who treated her well. Her responce was, "Sorry, but nice guys finish last." I'm not making this up either, those are her exact words. So you can't really be nice or apparently you won't get girls. I for one am way too nice so I guess I'm out there. Heck I'm in all 3 catagories.
There's one more catagory too. It's the "liking the same person for a long time and you gave them everything and you put all your faith in this and falling in love with someone who could never possibly love you" catagory. It's where you like someone and they'll play around with you, until you end up thinking they like you, but you don't do anything for a long time. So you watch as they go through different bf's/gf's and watch their bad break ups over and over until you think, "I know the signs they like me. I'm going to ask them out." Then they say no. Even though that should be it, you don't give up and you keep trying because, why not? Then something magical happens and they kiss you out of nowhere and you freak out not knowing what to do. Then when you confront them they say it didn't mean anything to them, even though it's your first kiss. So you keep going for them and they have no interest in you, but you think you love them so you never give up to try to get new girls.
The above is not me, thank god. It's just somebody that I knew a while ago.
So no, love isn't a waste of time, not by a hookshot. It's the one of the most important things you need in life. It's up there with food, water, and air. It's only a waste of time if you waste your time by being one of the four catagories above.
