Now that you have graduated, it is time to face a new life. You would need to find new jobs and think about your needs and bills. In short, it is time for you to be an adult and be responsible. But that does not mean you will neglect your social life. With busyness coming ahead, it seems quite hard to do it. But there are ways to do it, and it does not take that much effort. 
1. Stay in Touch
The best way to have friends after graduating is staying in touch with your college friends. This also includes others like your high school friends and from other places. This way, you can still have someone to talk to and know someone you can just hang out with and share stories with. You can have a get together when your schedules align. Also, this is also an opportunity to meet new friends if they have met someone.
2. Trying a New Hobby
It is never too late to try something new. This includes sports, arts and crafts, music, etc. The great thing about this is that you will be able to make new friends. It could be through classes where you can bond with someone who is also doing that for the first time. Some hobbies also have communities online or even locally. Not only you will have new friends, but you will also have someone to guide and help you with your new hobby.
3. Join Some Clubs
There are some clubs and groups of all sorts around. You can find something that holds your appeal. It could be something new that you want to try or just an old interest. That way, you will meet some people that share your passion and also some more fascinating people.
4. At Your Work
Having a new job may be intimidating but that does not mean it will stop you from befriending your coworkers. Some of them might be as new as you, and it is a great tool to get to know them because you are having the same experience at the moment. Also, it will be great to befriend some of the seniors. That way, you can learn more about your workplace. So if they invite you to go out after work or have lunch with them, grab the opportunity.
5. Social Media
Nowadays, you do not even need to go out to make some friends. With different apps and social media, you will be able to meet someone, and you do not even need to be in the same country. Truly, the internet made the world smaller. Because of that, you can easily make friends. You can set up a blog and that way, you can meet people that share your interest. You can also have some meetups especially if you discover that you just live in the same area. In fact, you can find people with the use of social media and if you are a person who gets awkward talking to new people in person, this might help you.
