Summarize this article in one sentence.
It isn't a set concept and it does vary for everyone. However, most people would find joy in relating to loved ones, spending time with people they care about and counting one's blessings. Write a list of the people, things and activities that bring joy into your life. Keep it simple, focusing on what is achievable. There may be things that you don't yet know about that will bring you joy. If you have a hard time determining where you can find joy, perhaps you haven't yet had sufficient new experiences to expose you to all potential sources of joy. Try new activities, meet new people and try new things. Join a new club, group, Facebook or Meetup group, sports facility, hiking group or overseas tour. Discover new things to try and meet new people.
Determine what joy means for you. Be adventurous.
