Your spouse is your strategic partner. He/She are your partners that will help you to manage your key activities (running the family) and key resources ( #finance, procreation) so that you may deliver your product (#values, services) to your customers ( #children, #parents, parents in law).
He/She helps you to deliver your product through channels of #communication, #advice and negotiation so that the customer #relationship(relationship with your children, parents) can be improved and maintained.
So, helping your spouse to grow – either through personal development, career wise, education – is, by and large, an investment into your happiness.
That, my friends, is the Business Model Canvas of life.
