Put yourself out there. To make friends you have to meet people, lots of people. If you're new in the community, branch out from just meeting people at your new school or job. Instead, check out local bulletin boards for activities that are going on locally. Attend one of the events and start talking to people.
Be friendly. When meeting new people, remember to smile, maintain eye contact and give a firm, but not overly aggressive, handshake. Be confident. Overly introverted behavior can come across as snobbish or standoffish.
Find common interests. Mention a few of your hobbies to see who shares the same interests. If someone does, build on that. However, if noone shares your interest, move on. Remember not to get discouraged and keep trying.
Listen to people. Pay attention to the people you're meeting. See each as a prospective new friend with a specific area of interest. Try to find out what interests each person. People appreciate it when others truly care about shared concerns and interests.
Have a small party. Host a get-together at your house. It can be as big or small as you like. Provide drinks and snacks, as well as a few movies or games to prevent any getting-to-know-you awkward interludes.
Wait to receive an invitation to hang out. If you have been the only one initiating contact, wait for your new friends to call. This will also give you an opportunity to meet your friends' inner circle. Hopefully, a few may eventually become your friends as well.
Rest assured. You're on your way to finding yourself a great group of friends!
