Have a bustling social life. If you want to be more friendly, then you have to spend more time with your friends. Spending more time around other people will make you be a more socially aware and sensitive person who is used to talking to other people. You should try to fill your calendar with parties, social engagements, group hiking, biking, or swimming trips, and other fun friend-filled outings if you want to be more friendly more regularly.[4]
To have a bustling social life, you have to make your social life a priority. Don't let work, school, or other commitments get in your way -- not too much, at least.
It's important to have a busy social life, but you should also remember to save some time for yourself. You'll need to decompress, especially if you're not used to spending so much time around other people.
