Applies to life too, but easier said than done.
That seems somehow wrong.
Part of deeply loving someone is really knowing them, and you can't really know someone if they don't share their deepest fears, frustrations, and angers with you.
And part of a life is, hopefully, deeply loving someone.
(Of course, the advice in the article still holds -- your investors and customers don't and shouldn't deeply love you.)
Hopefully is the key word here. One may or may not find a partner in life that shares their aspirations. The only person you're guaranteed is yourself.
