How can I make new friends?

Make yourself available. If you want to make friends, you first need to put yourself out there somehow in order to meet people.[1] If you just sit alone, friends might come to you, but that's not likely. For example, if you're still in school, sit somewhere with other people. It doesn't have to be a crowded table, but try to choose one with at least 2 other people. Join an organization or club to meet new people. This is a great way to find other people who have common interests. You don't necessarily need to have a lot of common interests with people in order to make friends with them. Some of the most rewarding friendships are between 2 people who don't have much in common at all. However, if you like a specific topic, try searching for a location where you can meet people who share that interest. Volunteer for a cause you care about. Volunteering is also a good way for people of all ages to meet others. By working together, you build bonds with people. You may also meet others who have a passion for changing things the way you do (a common cause). Try connecting with people you already know. Chances are, you already know a few people who could potentially become good friends. Consider trying to get to know your co-workers, classmates, or even people in your social media network. Look for opportunities to talk to people. You can join a club, go to school, or go to church, but you still won't make friends if you don't actually talk to people. By the same token, you don't have to be involved with an organization to be social. Any time you talk to someone, you have a chance at making a lasting friend. Don’t worry about saying anything special—just open a conversation by saying something friendly (like “Isn’t it a gorgeous day?” or “That is an awesome shirt!”) and see where it goes from there!

Making new friend is a skill you learn from your birth upto your death and keeping friends as a friend is even a tougher task. For making new friend the first thing is required to have confidence in itself talking to break the ice and mix with him/her. You can use the sub communication if you want them to approach you but I suggest you to break the ice because it reflects your confidence. Show them similarities which lies in you indeed. Show them how important you are for them and for the world as your existance is worth in this world and most importantly help each other with no dark desire in your mind. Keeping a friendship and maintaining it is a different concept in which you have to observe your friend behaviour time to time under many of your actions and conversation which teaches you what he/she prefers and what not. As I mentioned it's a different concept so we can about about it on the question. Best of luck in your journey to make friend. Having a smile on your face all the time is almost impossible without having them.
