First - make a list of "wildest dreams" - things you'd like to do, but maybe haven't because you were scared or thought you'd fail or it was too expensive or whatever.
Then - prioritize that list - according to level of desire.
Then - brainstorm a way to start pursuing one of those goals. Want to learn to scuba dive? Sign up for a class. Want to climb a mountain? Find a local hiking club and start training.
As for friendships - make a list of all your current or past acquaintances. Put a star next to people you think you'd like top know better, or would like to reconnect with. Make a plan to start contact with those people - make a lunch date, or invite a few people over for dinner.
Join a club or class related to an interest of yours - you'll meet people with similar interests.
It will happen, but you will have to plan and attack this problem like any other project if it doesn't come naturally to you.
