Be an avid book reader. You can’t be an interesting person if you can’t hold the other end of a conversation(unless it’s really boring).
Learn to cook. You must know at least three delicious exotic dishes that are not locally know. It’s not very hard since you only need to learn basic cooking skills and then learn a few recopies.
Travel, Go on adventures. Have stories to tell.
Don’t hide your passion. Talk about it and find ways to make it interesting to everyone you talk with.
Be interesting. Don’t be afraid to talk to new people. Initiate conversation. Talk openly and with confident.
