Circle one
You need a purpose and a purpose needs you. You should be a resource to a group or a thing.

Circle two
A good understanding and in best terms with a loving partner.

Circle three
A weekly meeting with your friends.

Circle four
A monthly meeting with your family.

Circle five
Mentees who walk a similar path as you.

With all of them in the picture, a man doesn't think about meaning of life, as he has it.
