As a relatively young entrepreneur that fell in love a year ago, and then had the relationship fall apart a few months ago, I found falling in and out of love to destroy my productivity.
I was in a multi month rut that I only crawled out of through therapy and understanding how to actually care about myself.
As much as I know that I'd be better at handling the situation after having experience now, the sheer awfulness of having to run a business while feeling heartbroken turns me off from wanting another relationship. I guess I understand now why so many entrepreneurs I know have messy love lives.
