Be intentional about starting conversations
Do not wait for others to approach you wanting to be friends. While this may happen, if you truly wish to start a friendship, take action! Make the first move! The worst that could happen is that it doesn't work out. Do not, I repeat, do not, sit around feeling sorry for yourself because no one will talk to you!
Do not limit yourself to those in the same stage of life as you
People from all walks of life have things to offer you. I personally have friends who are much younger than me and friends who are older than me as well. I also have friends who are single, those who are married, some with kids, and even empty nesters. I learn from those who have gone before me and share my knowledge who come after.
Find others with similar passions
Befriending those with similar passions creates an automatic topic for discussion! Make friends at your workplace, or those at the craft store you frequent. Talk to the people who share your pew each week at church. Meet friends in the dog park or the laundromat (everyone does laundry, right?)
Just be yourself
Be yourself. As an adult, you have no more time to waste by pretending to be someone you're not. On that note, though, continue to grow in excellence, making yourself the best version of you through the power of the Holy Spirit.
Accept that long-term friendships take time to cultivate
The friend you made last Tuesday is not going to have the same connection with you as the friend you have had since the 5th grade. Deep friendships take time to cultivate
