Do I believe everybody has a soulmate?

Wikipedia
Soulmate (or soul mate) is a term sometimes used to designate someone with whom one has a feeling of deep and natural affinity, friendship, love, intimacy, sexuality, and/or compatibility

I don't believe we can all have or need a soulmate. My answer is no.

Imagine you were wealthy, never had to work, and had a large mansion. How many children would you raise considering this environment?
